Whiplash
This movie can induce anxiety in its viewers! As a matter of fact, you are guaranteed to feel just as stressed out as Andrew does in the movie. He has a hard time living up to the task. On the day of the big recital, he almost misses the show. As a punishment of sorts, his teacher uses the wrong music on purpose. However, he manages to succeed in spite of this in the end.
Black Swan
It was amazing to watch the amazing Mila Kunis and Natalie Portman play ballet rivals in the show. However, the ending is pretty dark! After Nina stabs Lily, she heads out for the performance of Swan Lake. We then learn that Lily had been a hallucination of hers the whole time. This means that she stabbed herself! As she bleeds out on the stage, she notes that it is her best performance thus far.
