With this film, Jennifer Lawrence won the Oscar for best actress in a strong performance as the main protagonist in showing how she handles a very difficult role of insecurities, psychological conflicts, loneliness, a dysfunctional environment and the shared moments with a bipolar partner. I did not like (or understand) the film in its integrity due to the local theme and the mood it was transmitted in a very "American" way containing: the admiration for football, the strange mood of protecting society from patients with mental problems, aggressiveness in the conversation .... finally jokes, slang were not easy to grasp, much less to understand his humor if the viewer did not live in United States for a while ..... this causes you to lose much of what was presented. The music, the performance of the main actors and De Niro as a father is great, but still, I did not enjoy at 100%l. Much shouting, verbal abuse in a dysfunctional family, bipolar treatment, intensity of the characters ......, superficiality in life .......
