Please no.
The first movie was an insult to the book (which if you haven't read it already do so. it's a fantastic, quick read). And is anybody else skeptical about I Am Legend? I love the book and am a big fan of "end of the world" flicks but am a little annoyed by how Hollywood this one feels. I'm sure it will have a lovely magic dust ending like The Invasion where everyone is suddenly ok again. However it turns out, it probably still won't best Quiet Earth as the best last man on Earth film out there.
