Red State
Three horny high school boys come across an online personal ad from an older woman looking for a gang bang and, boys being boys, they hit the road to satisfy their libidinal urges but what begins as a fantasy takes a dark turn as they come face-to-face with a terrifying fundamentalist "holy" force with a fatal agenda.
Dare I say that Kevin Smith, of Jay & Silent Bob fame, may reinvent himself with his latest film, Red State? I certainly hope so. Not that I don't like Smith's films, most of them, anyway, but one can only go so far with "Snootchie Bootchies", if you ask me.
BTW, I realize that this is a thriller. I felt it would be better suited here since the Horror Forum is dead.
