Punch-Drunk Love (2002)

Barry (Adam Sandler) is a vaguely-unsatisfied toilet plunger salesman living a life of drudgery, his only contact with others his insensitive and emotionally cruel family. That is, until one day where a harmonium falls off the back of a truck in front of him, and his life begins to transform into a beautiful and surreal experience as he encounters a new love. He meets a mysterious woman, Lena (Emily Watson) and pursues her with reckless gusto, acting as irrationally as any man in love can do, and even destroying a restaurant bathroom in the process. Punch-Drunk Love is a genre-defying, romantic film that will make you smile and wince, often at the same time.
