Be warned: this is not a coming of age film about discovering your sexual identity. It's one big, violence-induced apology for bullying a lesbian girl.
Gaslighting, multiple (!) suicide attempts, homophobic slurs, violent revenge, ongoing bullying, harmful stereotypes - it's obvious not a single lgbt person was involved in making this movie. The teacher even compares same-sex relationships to beastiality.
The storyline focuses completely on the bully and leaves no room for the girl's story. Also the acting is pretty bad and the dialogues are completely unintelligible.
If you're struggling with your coming out, please don't watch this but watch Heartstopper. It can be confusing but it's not THIS horrible.
