Is that "Mean Creek" gag, i've never seen it but sounds like it might be the film?
I haven't seen "The Apple" either but from what i gather it's a so bad it's good naff cheesy musical that has something to do with Adam & Eve, God and all that stuff.
What i have seen are "River's Edge" that was mentioned and it's really dark but a favourite of mine.
Also i second that "Roar" is a film you won't believe was made till you see it, gasp as some hippy guy play fights with Lions and puts his family in peril by surrounding them with assorted big cats, and these aren't special effects it's pant shittingly real.
I've got the Blu ray as it's a film i always wanted to see as a kid but it kinda disappeared over here, the story is pretty much non existent, but it's mesmerising in it's insanity.
See a young Melanie Griffith with her head being gnawed on by a wild cat.
Apparently 70 crew members were harmed and most of the footage ends up in the film.
