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

While Jamey (Noah Centineo) is playing games with his brother, he has the XBox controller on his lap. On that specific controller, the light would be on if the console itself was on. The light is off when it's on his lap. Meaning they cannot be playing video games while the XBox or his controller is off. See more »


Dan: I have to find a story for my vlog. If I don't get into any college, I can sell my vlog to Buzzfeed or Vice.
Sierra: Or you can bank on your straight As.
Dan: What is this, the 90s? I've got to create Google 2.0, or swim backstroke while playing the violin at the Olympics. Or create a new species of cat while volunteering in a third world country at the same time.

Awful movie - how can i route for someone doing something so awful
8 September 2018 | by rkelliott-653-550617See all my reviews

I really hated this film. I get what they were going for but it was terrible. She lies pretty much the whole way through, kissing him without his consent. cat fishing doesn't make a romantic storyline. just horrible through and through.
