Vera Farmiga wasn't too wasted here, though she had to play the stereotypical depressed mother everyone hates. Especially when she was fearing for the baby. Still no idea why Lily was constantly crying when Joshua was away.
After all the entirety of this hate filled paranoid trip the pay off in the last minute or two tells us what we'd suspected all along in a nice patronizing song.
I haven't been angered by a movie in quite some time but this one did it well...so there you go, avoid at all cost.
