Butting in here, but "Dead Lesbian Syndrome" is definitely a trend. I remember discussing it in my queer lit class in college - particularly in reference to pulp novels in the 60s, I think. You'd have one girl kill herself and the other goes back to the straight and narrow path, if I'm remembering correctly. Of course, the trend has definitely continued since then, or you wouldn't have so much source for the vid.

Anyway, I thought it was really cool how you had all those different trends and such (your cliches) in the vid.
