Course language aside (not fond of the "F" word), you almost felt like you were a voyeur, rather than a patron in a movie theater. The acting is so real....it's not acting. Two very disturbed people find that they are the only one who gets the other. Robert De Niro was perfect as an eccentric OCD character - played so real. (M son is OCD). Loved Jennifer Lawrence and Bradley Cooper - such chemistry!! One of my favorite movies of the year.
