I Am Legend.
Watch it on youtube Monday night. It's in 17 parts. I was really excited about it given the great trailer and premise. I even read the wikipedia summary of the original book and it seemed good.
But there are too many plot holes, not enough action, the story meanders in parts and the ending is very unsatisying. It's not a bad movie, it's just disappointing to watch something with so much potential turn out so humdrum.
Originally I Am Legend was supposed to be a Arnold Schwarzenegger film back in 2000 but they couldn't get the studio to sign off on the budget. I am guessing they wanted to blow too much stuff up.
