Whiplash
Wiplash starts out slow but don't let that fool you this film is a roller coaster of emotion that ends in not a bang but a whimper. The way this movie keeps you in a claustrophobic room and shows realistic mental wear on a person going through abuse is perfect. We see him start out normal and obsesse over his drumming to the breaking point and where it shines most is his rise to accomplishment where the question is do the ends justify the means? Did either party really win? It doesn't matter because the movie doesn't have to end in a grandiose way it just lets you sit on these questions and give an amazingly melancholy conclusion.
