It was just an OK movie to me. The characters and the script did enough to keep my attention but it was boring in some parts and I expected more. It didn't get exciting until the end, which became pretty much a typical Hollywood ending.

Two great things about this film, though: (1) The awesome chemistry between Bradley Cooper and Jennifer Lawrence and (2) The authenticity of someone battling bipolar disorder. (Much better than how it was portrayed in Tyler Perry's dreadful "Acrimony".) The character's mental illness was very similar to what I've witnessed with an ex-boyfriend and other acquaintances who have BPD.
