Initially mistaken for a psychotic thriller, the main character Sierra Burgess goes on wacky misadventures as she catfishes a guy she likes, humiliates a girl who was nothing but nice to her because she ended up with a girl that Sierra doesn't deserve and sexually assults said guy. Wow, what a romantic movie. Written by A Communist

Upon further thought
10 September 2018 | by crazygowooSee all my reviews

I think this movie really has some problematic points and makes it a point to excuse some pretty dark behaviors. Like what I want to move this forward and down to a 6 after what I read on Twitter. This film is so tragic. Plus the movie was weird in the end anyway and the pacing was off.
