Edit: screw it, it gets 5 stars. Original review:
One of those films that is this close to being a 5/5 for me. Wow. Everything in it is close to perfect - Lenny's direction, Brie Larson's incredible performance, the close ups, the editing.
I found the structure of the film really interesting, with the climax occuring at the mid point of the film. Definitely preferred the first half (as it seems most people did), but I don't think the criticism of the latter half is fair.
Seeing the world through a child's eyes is one of the most beautiful things to see cinematically, and it's done so well here. Why am I not giving this 5?
"Director Lenny Abrahamson saw more than 2,000 child actors before he came across Jacob Tremblay's audition tape." - IMDB trivia
