I recently subscribed to Shudder and it has a decent selection, but most seem to be campy horror flicks. There is a neat series called Cursed Films that covers the tragedies surrounding The Exorcist, The Omen, Poltergeist, The Crow, and The Twilight Zone movie. Check it out if you guys can. Some of the episodes do go off on a tangent, and The Twilight Zone segment about the helicopter accident is a bit hard to watch.
I watched that film a few years ago not knowing what to expect. It's definitely worth watching as a film alone, though the horror aspect may turn some people away since it comes out of nowhere and hits hard. I also recommend this movie!
