Simply outstanding(!) and far better than what professional critics and amateur reviewers say. It's really one the best animated films of the decade. If you don't want a musical but prefer superhero fighting, ok, it's not for you. But in terms of originality, laughter and songs, this is the best animated film. I've seen probably more films than most critics and seen the best, so trust me on this. I will go through some critics points which I don't think are valid.
1. Originality and moral theme: Sing has multiple storylines and they move quickly so it's hard to focus on one moral line like the Lion King or Monsters, Inc. But each story has a terrific line which are not necessarily trite cliches. For one, Rosita is an overwork mother pig with a ridiculously large family. Frankly, I have never seen a story line like that since one of those movies from the 1960s or earlier (e.g, Yours, Mine and Ours). But it's a funny take on a multi-tasking mom who wants a life outside homemaking. Meena is the shy elephant who can sing but is afraid...I don't know any movies that carry that story line unless one means the reality shows where we find a Susan Boyle or two. I have not seen a Buster Moon dreamer in a movie in a long time. You could compare the storylines to one of those 70s movies on dancing but this is different. Ash fires quills when she sings, Buster acts as a carwash mop, Ms Crawly is always losing her glass eye. Tell me you have seen all that in other movies. I'm sorry critics. This is a very original film. And the storylines are terrific: overcoming fear, shyness, learning to stand on your own (from your boyfriend), learning not to just be an overworked mom, trying to face up to your dad, live up to your dad, dream. I could stop there, but I wonder what people missed?
2. Humor: people seriously thought it wasn't that funny? Miss Crawly's glass eye? Buster Moon and the moon? Gunter dancing? Rosita in the supermarket? The baboon Mike attacks? Buster wakes up in...? It has far too many funny moments, almost nonstop especially with some characters.
3. Songs: it's a unique film since Reese Witherspoon, Seth MacFarlance, Tori Kelly join up with Jennifer Hudson, Stevie Wonder and Ariana Grande...and the songs are terrific.
Aside from that, the animation and direction were terrific, as good as any animated film. The characters, squids and the flood were exemplary in outstanding animation.
Ok, the plot was relatively simple even with the running storylines.
If you don't like to laugh, don't want to hear a great soundtrack and songs, and a fast-paced movie, then this isn't for you.
