No, haven't seen it yet. There was very little promotion around it when it was released, which surprised me. I think it only played in art house theaters when it came out.
All of the original actors and worth a watch.
That and no re-watchability (not sure that is a word) because he goes for the big twist... Sixth Sense, Unbreakable, etc.
I don't know, I will watch Sixth Sense again from time to time if I see it is on and near the beginning. It isn't one I'm drawn into watching if it is well into it, though (unlike Dune where I'll gladly watch the last 5 minutes, the whole thing or any portion in between, for some reason).
