It's no definitive masterpiece but it's damn close.
This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.
It's the kind of movie you'll want to see a second time with someone who hasn't seen it yet, to remember what it was like to watch it for the first time.
A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.
