I thought the acting was done very well. However, the story would have been more interesting if there was more background to understand how Dall became so entrenched in her obsession to win. I get that in real-life OCD cannot be explained…but, in this movie giving more insight to her history would have helped in building out the character. The end of the movie left you hanging and not in an intriguing and thought-provoking way. It was like…all of that and this is the end?
