We went to see I Am Legend today. It's well worth seeing albeit unrelievedly bleak; the bleakest mainstream Hollywood movie I've ever seen. It's even religious.
But it's also the first movie I know of that takes the position that what the world really needs is 6 billion fewer humans, more or less. There is, at the end, in the background a perfect Gaian touch that will unite religious and environmental zealots in wishful sighs.
