Loved that movie. Saw it at Film Forum in 2004. I don't have a television, and obviously I'd never seen Third Rock (still haven't), so when a friend and I went to see Mysterious Skin, and (before the show) he said "This is the kid from 3RfromTS, I said, "Who?" (or, rather, I probably said, "So?") and immediately afterwards, I said, "Holy Shit!"
That was a good movie.
