If there was ever a movie to scare someone out of EVER doing drugs, REQUIEM FOR A DREAM is it.  This movie is truly like watching a nightmare, as we follow different addicts spiral down toward oblivion because of their addictions.  Ellen Burstyn is truly a marvel as the elderly lady who starts on diet pills and gets worse, and worse, and WORSE.  I also enjoyed how Marlon Wayans wasn't a complete psychotic idiot like he usually is in comedies.  Darren Aronofsky is one weird, but talented filmmaker.
