They added a bunch to the instant watch list: spiderman 3, superbad, corpse bride, ghost rider, etc.
Edit: Sorry, meant to add this to the general Netflix post.
As for sleeper hits; I really enjoyed King of Kong and watching the first season of Star Trek (Never watched it before). I just added a ton to my list and found "paper clips" a documentary, if memory serves, about a Kentucky (?) school collecting a paper clip for each of the people killed in the Holocaust. I teach a unit on Art Spiegleman's Maus in one of my Lit classes and I have heard good things about this documentary in my research.
