There's something about this movie that, when you walk out of the theatre, makes you smile and want to say "now that's something I haven't seen before!"
Perhaps, it's the 'mockumentary' format... something I was really dubious about when I first read about it, but is done extremely well. There's something about the looseness of the camera, the way the shots are staged... some of the best gags come from the fact that this film isn't being setup like every other animated movie on the block.
The character designs are great--love the kinda sport and Hawaiian feel in the penguin colouring. The story probably isn't the most original thing in the world... basically your friends and having fun are more important than any trophy... but somehow it really feels fresh. The characters are charming--the three kids come very close to the 'Happy Feet' baby penguins in cute factor. Even the sporadic bits of 'poop' humour didn't bother me nearly as much they have in other movies.
And my god, the visuals... yes, the movie is about surfing penguins so clearly, water is kinda important... but that was the most stunning water I have ever seen in an animated feature. The surfing looks and feels spectacular--like the idea of penguins surfing is the most natural thing in the world.
The best thing about Surf's Up is the fact that it isn't trying to be every other animated feature. It isn't beating you over the head with how "wink-wink, nudge-nudge" funny it is. It isn't beating you over the head with a gooey message. It's not afraid of being what it is--a smart, charming piece of work.
This is Sony Animation's first feature and, if they keep up this kinda quality up in terms of story, look and originality, I think we've finally found a studio that can give Pixar a run for its money.
edit: apologies... Sony Animation's SECOND film... Open Season looked so unappealing I didn't even note which studio it came from.
