Blue Valentine

Blue Valentine is a very sad, very difficult move to watch. It stars Ryan Gosling and Michelle Williams as a young married couple whose relationship is falling apart. Both actors give marvelous performances.

The movie zeroes in on the the tension between them, almost microscopically. It also veers, through extended flashbacks, to the sweet beginning of their courtship. It does both these things very well, but there seems to be something missing. How did they grow that far apart? Did she just become sick of him (he still seemed crazy about her)?
