Goodbye Christopher Robin is a sad bittersweet story behind the creation of Winnie the Pooh.

Writer Alan Milne (Domhnall Gleeson) returned home after World War One suffering from shell shock and anti war sentiments. He wants peace and quiet for an environment where he could write. He decides to move to the country.

As his self absorbed wife Daphne (Margot Robbie) goes to enjoy the London high life, nanny Olive (Kelly Macdonald) goes to visit her ill mother. Milne is left to look after his son Billy Moon. As they walk in the countryside Milne creates stories based on his sons toys to entertain him.

The Pooh books are a big hit but the publicity has a negative effect on Christopher Robin as he reaches adolescence that causes a rift with his parents.

As a child I read the Winnie the Pooh books and I was aware that Christopher Robin was a real person who was still alive. The fact that he never appeared on television to discuss the books or his life was a clue that he wished to remain distant from the creations that bought him fame.

The film was a strange mixture. A damaged war veteran, a selfish wife, a cute kid and the initial creation of the creatures Winnie, Tigger, Eeyore and Piglet that enchanted generations kids. It is not a children's films but as it finds its groove, a magical spark, it moves to another level where we see the negative impact of the publicity on young Billy Moon.

The film itself is all chocolate box nostalgic. Everyone is well dressed and presented, no poverty to see here.

Christopher Robin's parents do not come across well in this drama, especially the mother. The film never reallys gels and the film comes across as contrived to give it some kind of satisfactory ending which seems far removed from the truth. It should had mentioned that Alan Milne modified his anti war views and served in the Home Guard during World War Two.

A.A. Milne's Winnie the Pooh stories captivated me as a child and they are still wonderful stories through young adult eyes. The stories epitomise childhood innocence, the atmosphere is enough to enchant everybody regardless of gender and age and the characters are some of the most charming in children's literature (Disney's treatment of them as some of their most famous ever creations is every bit as special).

Hearing that there was a biographical drama based on the man, his life and his family, the desire to see 'Goodbye Christopher Robin' was overwhelming. Was not disappointed at all after seeing it today, it was a lovely biographical drama even with Milne's life not being what one would expect reading the stories or being familiar with the timeless characters, his dark and troubled personal life being the anti-thesis of the innocent and charming world created in his Winnie the Pooh stories. That was actually what was so fascinating about 'Goodbye Christopher Robin'.

'Goodbye Christopher Robin' in biographical terms fascinates and illuminates. But the film fares even better judging it as a film on its own merits, on this front it is a lovely very good film that is neither the potentially cutesy cookie-cutter film one might think it would be reading the title or the overly dark and joyless one that one would fear upon looking up what the film is about. It's more layered than either.

The film looks great for starters. The beautiful cinematography, with its vibrant hues, really brings the film to life in a way that reminds one of how a story book would. The settings and costumes are both sumptuous and vivid, making the viewer feel like they've been transported in time to that period and being part of it. Carter Burwell's string-heavy score is luscious and stirring in its elegance. Both combined creates a really nostalgic quality that could have been at odds at the dark portrayal of Milne's and his family's personal life but it's an effective contrast.

When it comes to the writing, 'Goodbye Christopher Robin' is very intelligently and thoughtfully written and, considering that it has a subject matter where it is so easy to go heavy-handed and be too much of one tone, has evidence of sensitivity and nuance with touches of bitter irony in how such a happy childhood depicted in the stories was very much a miserable one in real life. The nods and references to Milne's work are clever and affectionate, enough to make one's eyes well up with aching nostalgia. The story is cohesive and never feels like it's jumping around too much or lacking momentum, it also has a lot of heart and affecting poignancy in how Christopher tries to get his father to loosen up and the interaction with his nanny (along with Christopher the warmest and most sympathetic character in 'Goodbye Christopher Robin').

Direction lets the story to breathe but doesn't fail in giving it momentum. The performances are near-uniformly strong. The central character in fact is Christopher Robin himself, and while Alex Lawther does very well with teenage Christopher the star here is Will Tilston, who gives a touching and far more layered performance than one would think he was capable of. Instead of being overly-cute, he evokes tears of both playful joy and vulnerable sadness and the film particularly comes alive with the father/son relationship.

As Milne, Domhnall Gleeson is excellent, whether one feels empathy for him is another story but he portrays Milne with an appropriately straight back and reserve and he is every inch the troubled figure. The levity of the story comes in the nanny character played by Kelly McDonald, the warmth and charm of her portrayal is much needed and her common sense invaluable.

By all means, 'Goodbye Christopher Robin' is not without short-comings. The biggest one being the one-dimensional and without-redeeming-qualities character writing for Daphne which consequently makes Margot Robbie portray her far too firmly and coldly, even in the subject matter these approaches didn't gel.

Short-coming number two is not buying and being put off somewhat by Milne and Daphne's far too casual, uncaring even, attitude for Christopher's welfare. This is something that makes one endear to them even less.

Overall, lovely, moving film. 8/10 Bethany Cox

The thought of a biopic that charts the touching story of the creation of a children's tale that has meant so much to so many over the years instantly makes me think of Finding Neverland, a sweet film I'm very fond of. In many ways, Goodbye Christopher Robin is very similar – bitter-sweet, heart-warming, full of nostalgia; you could easily swap Johnny Depp for Domhnall Gleeson and Kate Winslet for Margot Robbie (although the characters differ greatly). Although this story behind Winnie the Pooh doesn't contain quite the same childish magic and glee that the story behind Peter Pan gave us, it's still a delightful, emotional story told in a joyful, touching way.

The film as a whole addresses several themes and it's really a bit of a mishmash – it's not just about the creation of the Winnie the Pooh books; it's about the impact of war, the troubles with early 20th century parenting, tricky father-son relationships, the joy and innocence of childhood, and the pain and price of fame. This all works as both a strength and a weakness of the film; in many ways it's wonderful to have such a wealth of topics and the variety keeps things fresh and interesting. On the other hand, some themes aren't fully explored to the extent they could be and it feels as though it's missing something occasionally. It never really focuses on one theme and so does tend to meander around all these topics, telling a vague story; at times it seems to be more a series of scenes with just a semblance of story. Of course this is because the story itself is fairly simple, so it's nice that they enriched the plot with so many themes; it just feels as though it could have benefited from a little more detail.

Nevertheless it's a film that's a joy to watch and brings with it a load of emotions – sniffles and tears seemed to permeate the cinema. This is down to a couple of things; firstly the characters and the story they go through together; but more than that all the references (some obvious, some subtle) to Winnie the Pooh and the rest of Milne's work. From small quotations and images, to creating a little wooden hut to house one of Billy's toys, there are plenty of nods to Winnie the Pooh and these can't fail to bring a nostalgic tear to anyone and awaken fond childhood memories. The childhood especially is heavily romanticised and anyone can identify with Billy Moon in some way, bringing to mind all the happiness and innocence we experienced as children. This is all complimented by beautiful cinematography, making the wilds of Ashdown Forest seem absolutely stunning and really strengthening the magical quality of childhood and its inexhaustible supply of imagination and charm. In fact it's this middle section where the world of Winnie the Pooh is created that is the strongest part.

There aren't a great many characters in this film, making it all seem more intimate, allowing us to grow attached to the characters – though at times this can be challenging. As excellent as Gleeson is, it can be sometimes difficult to understand and empathise with him as his character is so stiff and reserved; still Gleeson gives us a wonderful contrast to this and how time with his son helps him to loosen up and re-discover his 'inner child'. Margot Robbie's Daphne comes across as a missed opportunity. Stunning and beautiful as always, it's hard to imagine Robbie playing a detestable character, but this she manages to do and do well. It's just the writing doesn't really seem to do her credit as we aren't given a real insight into her character. Kelly Macdonald and Will Tilston do shine though. Macdonald's Olive grounds the film as the friendliest, least complex adult character and Tilston exceeds all expectations you would have from a nine year old in their first ever acting role. Sheer innocence and childishness emanates effortlessly from his big eyes and little movements. He really is the heart of the film and fortunately they make the most of him. Sadly every boy has to grow up, but Billy Moon's 18 year old self played by Alex Lawther fills the shoes of his younger counterpart well, giving us the necessary angst and emotion needed.

Perhaps not quite the early Oscar contender I hoped for and it lacks some of the magic that I loved in similar film Finding Neverland. However, this is still a great film, dripping with emotion, nostalgia and a romantic view of childhood; exploring a wealth of themes and with some excellent performances (particularly from the titular Christopher Robin) and affectionate references to a childhood classic, Goodbye Christopher Robin is a lovely, bittersweet film for the whole family. Bring the tissues – this one's going to move you.
