Oh that's subtle...
I literally just finished watching this (credits are rolling)
Neville gives them the bottle of his blood, and then collapses, and takes a perfect Jesus pose, lol very subtle
anyway, it was interesting. I have not seen I Am Legend yet, but I could see where this followed the book (Actually, it seemed like the first 40 minutes of it could have been the book. Neville going about life, killing the "family" members, then finally being captured, and told that he is the monster)
"Why would they want the Duke's...son killed?"
