I just finished watching The Final Girls on Netflix.
It's a silly love letter to the classic 80's slasher flicks, and centres on Max, whose scream queen mother died three years earlier. She and some friends attend a feature showing of Camp Bloodbath, a cheesy horror movie her mom appeared in back in the day. An accident lands them in the universe of the movie, and the group finds they are forced to adhere to its general structure. Such as not being able to just, y'know, leave, when they realise there's a machete-wielding killer in the forest, and hearing the soundtrack that signifies his presence.
While I think the PG 13 rating does hold it back a bit, overall I can recommend The Final Girls. It lampshades a lot of the slasher tropes quite well (terrible dialogue, inexplicably invincible killer, sex equals death), there are also some genuinely moving parts, what with Max interacting with a young version of her dead mother.
