I loved this movie. Loved,loved,loved. The dialogue is fantastic. The storyline about mental illness (bipolar in particular) is hopeful and truthful. There were supporting storylines that are so true of someone suffering from bipolar. The "good" relatives who sabotage health, the overprotective parent who enables, etc.
However, none of this is in preachy form. It's just in the story and that is a well-written film. I understand the book is good, but different, so I will have to read that now. I was shocked that Bradley Cooper had the acting chops for this role, but he was fantastic. As was DeNiro and Jennifer Lawrence. It was a charming movie about what we all must do "have a plan" to navigate the hard times in life. I highly recommend. (I think there was a lot of swearing, but be warned, I don't really hear it, so I'm not sure. My ears just tune it out.)
Really well-written movie that relies on character and story. Loved it.
