totally fucked up (1993)
"Gay, alienated Los Angeles teens have a hard time as their parents kick them out of their homes, they don’t have money, their lovers cheat, and they are harassed by gay-bashers."
the most normal out of all of them and still strange
the doom generation (1995)
"Jordan White and Amy Blue, two troubled teens, pick up an adolescent drifter, Xavier Red. Together, the threesome embarks on a sex and violence-filled journey through an United States of psychos and quickie marts."
can't even tell you how excellent this movie is without spoiling it. make sure to watch this version (the unrated version) and not the one that was butchered for the R rating
nowhere (1997)
"Described as “90210 on acid”, the film tells the story of a day in the lives of a group of high school kids in Los Angeles and the strange lives they lead."
