For what it's worth, I enjoyed this one more than Midnight in Paris and Blue Jasmine, Woody's latest "celebrated" films.
The film has three things going for it:
1. It doesn't take itself too seriously. It aims to entertain, show a particular world and tell a good love story. And it doesn't tell you where it's going from the beginning, which makes the whole ride way more interesting than something like Irrational Man, where five minutes in you already know what will roll.
2. Storaro's work is beautiful. There's a candlelight scene about half way through, very simple, but powerful. It's a delightful film to just watch; colors, movements. Really good stuff.
3. The cast is awesome. Everyone is great, really. Some critics claim the film belongs to Stewart, and she is terrific. I hope Woody casts her more, and I hope she does more comedies. She really nails every single line in this. But Eisenberg and Carell are great too. There are a bunch of scenes which made me laugh out loud, particularly one between those two. You can sense the actors are enjoying the scenes. And all the supporting cast does this too. I don't know what it is, or what it depends on, but the film just works.
Also, the ending is great. I'm sure I'll revisit it soon. Not to be missed.
