I liked it, but not sure it's the unimpeachable masterpiece some are making it out to be. I was never really bored by it per se, but don't think it necessarily has to be three hours. Some of the tragedy here feels a bit written and contrived too. A guy who loses his child, then his wife dies far too young happens to be placed with a driver whose mother was killed in a freak avalanche? That's a lot of tragedy for two people. I mean sure it's possible, but I dunno, feels pretty scripted.
I also didn't like the final scene. I think it should have ended when Uncle Vanya ended, faded to black, cut to credit roll. I do LOVE Chekhov, so in that respect the movie is after my own heart.
