Okay, so after years of just hearing about this film and not seeing it (I have no excuses) I finally put it on. And wow, it's an absolutely fantastic film.

Ill start by giving my reason why I haven't watched for so long and that's because I was told it was really complicated and confusing. And I'll be honest, 10 minutes into this film I was completely out of whack. I had absolutely no idea what's happening. But after around half an hour or so it becomes really apparent what's happening and the story just becomes more and more interesting. So if you're worried about complexity of the plot. Don't, you'll be fine.

The ending as well I liked. You honestly don't know how this film will end, I was 10 minutes from the film ending and I still didn't know what was going to go down. But it's done really nicely and closes off any unanswered questions. Watching films like Donny Darko you end up confused by the end and have several questions whereas this doesn't have this and I prefer that. (Donny Darko is great by the way, I was just giving an example).

Beyond that I thought the acting was really good, the managed to pull off good character development and the changes of memory were quite obvious so there wasn't any overlapping or confusion on what you were watching.

It's just overall an absolutely fantastic film and I highly recommend watching this if you haven't done so already.

Evan Treborn suffered blackouts as a kid, especially when a traumatic event occurred. However as he grew up and moved towns these blackouts subsided and seems to be a happy kid at college.

When he starts reading journals he kept of these blackouts when he was a child. He finds that he is shifting in time that coincides with these blackouts and also the past and future timeline for himself and the people around him changes.

This is actually a surprisingly clever time travel film and in my opinion deals with some hard time travel concepts where you enter a world of multiverses, split future events, chaos theory and whether you can successfully change traumatic events.

No wonder poor Evan is left confused. If only he watched more Twilight Zone as a child or even Doctor Who he might not had made such a mess of trying to use his powers to fix the past and present.

Ashton Kutcher who is more known for comedy and light romance. He tries his best to muster some acting chops but it is passable, it could had been better with a stronger lead.

Surprisingly, this was a script that was knocking about for some years and it was only Ashton's involvement that gave it a green light.

It starts out puzzling and sinister but leads to a satisfactory thrilling ride as the movie starts to make sense as it progresses.

Evan Treborn (Ashton Kutcher when adult) blacks out painful memories since he was a kid. Although being the beloved son of Andrea Treborn (Melora Walters), he misses the presence of his father, who is an intern of an institution for the mentally ill. His best friends are Kayleigh and her brother Tommy, and Lenny. When Evan is about seven years old, he is advised by his doctor to write a journal, as a kind of memory exercise. When he is about twenty years old, he decides to read his notes, and realizes that he can travel in time and change his past. However, when he does it, the reality in the present changes too much, affecting the lives of his mother and friends. Evan tries to improve their lives, but he realizes that he is not God. This movie is presently in the movie theaters of Rio de Janeiro, but yesterday I rented an imported DVD. I saw the `Theatrical Version', and I found an excellent, unpredictable and intriguing screenplay. The story hooks the attention until the last scene, and it is amazing the great dramatic performance of Ashton Kutcher, since I am used to see him in comedies (`Dude, Where is My Car?', `Just Married', `My Boss Daughter' etc.). I saw also the deleted scenes, with the `Stalker Ending' and `Happy Sappy Ending' (which I liked more). This weekend, I intend to see the `Director's Cut Version'. I highly recommend this film. My vote is nine.

Title (Brazil): `O Efeito Borboleta' (`The Butterfly Effect')
