This movie was very well acted and the story was compelling, if a bit slow in the middle. Ooverall the film did a good job of conveying the unpredictability and difficulty of every day life with a family member with bipolar disorder. (I think the reality is a bit uglier, but this was a film not a documentary. ) Bradley Cooper and Jennifer Lawrence were both excellent as was Robert DiNiro.
This movie was terrific. In the first 5 minutes Pixar manages to create such a strong attachment to the couple in the opening scenes (don't want to spoil it by being too detailed) that I found myself bawling and laughing in alternating breaths. And they are ANIMATED characters -- not even real humans. At any rate, this is a first rate Pixar effort. I would caution that there are parts that are downright sad and some mature themes -- divorce, deadbeat dads -- that may be hard for some children to get and hard for others to watch, but with that caveat I would highly recommend spending the money on this one.
