Hmm I liked Dawson's Creek. It was amazing for me to see a gay person on the TV for the first time. Yeah I know not really High School but it started that way. I am just finished watching G.B.F (Gay Best Firend) and it is fun. I watch high school movies whenever I can find them as they tend to be fun to watch. The ones coming to my mind at the moment are Easy A and John Tucker Must Die. Probably people will think I am mad or something also love High School Musical series.
Heathers 2:37 Entre les murs Although none of them really have much to do with each other, other than that they're set in a high school.
I will guiltily admit to watching Glee. Freaks and Geeks is awesome, Rushmore/Clueless/Elections are really good movies.
