Summarize the following movie reviews:

1. The Upside of Anger isn't as good as any of its actors.
2. A drama mined with comic moments, the movie's got an Oscar-worthy performance from three-time Oscar nominee Joan Allen.
3. While most of the movie has a welcome feel to it, the ending carries as much absurdity as anything in Diary of a Mad Black Woman.
4. Any disappointment I felt about elements of this movie was overshadowed by the fine performances of Kevin Costner and Joan Allen, especially the latter.
5. Allen and Costner have the kind of genuine, unquestionable chemistry that can't be faked
6. Do yourself a favor and catch this fine film on the big screen.
7. There's no downside to the crackling Costner/Allen pairing, but Binder spreads himself thin. He puts in play too many subplots about Allen's budding daughters.
8. Achieves a harmonious balance between truth and consequence.
9. If you're in the mood for a well told tale of dysfunction and discovery, seeing this simply doesn't have a downside.
10. The downside is the slow pace of the movie.

Summary:
A comedy/ drama for grown-ups, with fine performances by Joan Allen and Kevin Costner.
