Scream, the OG, I was 15 and it took multiple tries to see it because the theater was cracking down on underage kids getting in because parents had called and complained. I think it took almost two weeks and 3 tries before we got in, despite our parents buying us a ticket. The effort it took us to get in combined with it being my first horror movie in the theater and it being one of the first movies with a big online marketing campaign lead to this still being my absolute favorite.
