Was there a bad performance in this film?

No. This movie was so well acted from top to bottom even with some very difficult roles. Of course its helpful to have a well written story.

I agree this is one of my favorite movies that I own and highly recommend to everybody, because of the recognizable mostly female ensemble and brilliant acting.

It's a really dark film, but people are always greatly thankful for bringing it to their attention.
