He is young. If he is serious about his craft he will learn from his mistakes. I guess I won't be seeing it though, everyone so far hates it. Oh well, better luck next time.
Don't base what you'll see on that. Most of the folks here who hated this movie, loved Signs. We were bored to tears by it and I didn't think it was all it was cracked up to be(and we only went to see it after the glowing reviews on this site I believe). We also loved Unbreakable.
Probably the best way to gage it is to see what other movies the folks criticizing it liked and disliked vs. what you did and judge it based on that. The fact that those who rave about Signs hated it, makes me want to see it since I like Signs the least out of all of his films so far.
BTW, I was scared silly with Blair Witch. I just let myself get into the moment in it and was watching it alone in the dark in my bedroom so I had a blast watching it. Others hated it. Everyone has different tastes.
