Using crass language & stereotypes isn't necessarily hateful or promoting violence. Laughing at our differences and accepting absurd social phenomenon and vernacular can disempower negativity and bring us together for deeper things we all share. Shane is very funny and I have seen no indication that he has ill-will towards anyone.
Barely scratches the surface of documenting what 4chan and its users are really like. However it wasn't completely out of touch and boomer'ish so I will give it a pass, somewhat.
The action is pretty good but there is not enough of it. There were way to many time jumps and the movie was too long overall.
Talk about laying it on thick.
