Movies like Ken Park and nightmare on elm street?

My goodness, I freaking love the original "A NIghtmare on Elm Street" series. And yes, Wes Craven is the way to go. But if you're looking for drugs, sex, and teenagers, checkout "Requiem for a Dream" (it's not a horror movie and it's not about teens, but it has all the sex and drugs a mind can handle), "Freddy VS Jason", "Idle Hands", the new "Halloween" is full of that stuff. Just to name a few...
