Decent to great instant titles (most of the best have been gone over long ago) I've seen recently and didn't mention earlier (can't guarantee all are still instant).
Cave of Forgotten Dreams (Werner Herzog's new documentary about Chauvet Cave, a cavern in southern France that contains the oldest human-painted images yet to be found on Earth. It's characteristically profound. )
Norm MacDonald: Me Doing Stand-up (any Norm fan will be pleased).
The Virgin Suicides (Was a bit too teen romance for my tastes, but the GF liked it and I could tell it had good technical merits. Could have used more suicide).
Midnight Cowboy (the first X-rated film to win an Oscar -- writing and directing. It's 1969 X-rated, but still a pretty bad ass classic. It obviously looks old but it doesn't feel stodgy like some old films. Great old school ghetto feel, with experimental parts that still feel fresh and characters so colorful you'll want to adjust the tint)
Patrice O'Neal: Elephant in the Room (pretty hilarious. RIP)
Iron Man: Extremis (motion comic with a way different feel than the movies, which I consider popcorn fare -- first one was fun enough though. Maybe I just liked it because I was stoned and it mentioned DMT, but seemed entertaining at the time).
Blue Mountain State Se 1 & 2 (I hate football, but find this hilarious in a silly way).
The Thing (Fun 80s horror about the ultimate evolutionary monster)
Some Folks Call It a Sling Blade (the short the movie was based on)
IP Man 1 and 2 (mostly 1, though)
