Eighth Grade is a cringe movie but it's all cringe generated by the main girl character herself (I'm already blanking on her name--Hayla or something like that.) Much of the movie is a non-preachy commentary on social media and its effect on young people, but one thing it's definitively preaching is that kids are all totally buried in their smartphones now, which means there's actually no obligatory bully character or bullying scene, because the pretty rich girl who the main character is jealous of is too buried in her smartphone to be mean to the main girl!! Absolutely nothing truly awful *happens* to the girl, except for a jerk of a boy who lamely tries to get her to take her shirt off in a game of truth or dare (she freaks and runs off crying, which is cringey, but think what a typical Hollywood movie would have done with the scene by comparison.) She's just really socially awkward and scared all the time.
It probably is one of the most accurate movies about being 13 I could possibly imagine, which is why I probably will never revisit it, because 13 year olds' lives aren't very interesting, particularly these days.
