Very slow pace and a lot of unanswered questions and an unconventional narrative. That sometimes can't even be called a narrative, really. And one thing that characterizes him is that when his films end, you're likely to go, "HEY, is that ALL? That didn't end, it just STOPPED," but given time to think, you usually can see that it did end, just not the way most directors would have ended it.

It's okay not to like Haneke -- he's idiosyncratic, and not for everyone -- but personally, I worship him.
