I'm probably going to get killed by the Will Smith fans (of which I am one) but here goes. I thought this was, at best, an ok movie and not even close to bringing out Smith's talent. He comments that all traces of humanity are gone from the creatures but then they set a trap exactly like the one he used? Plus, to me, the CGI effects were rather poor. When he was being chased/assaulted/attacked by the "night people", I didn't see scary bad guys, I saw badly done cartoon characters. If I want to watch this movie again, it will be the 1971 version starring Charlton Heston in "The Omega Man" which I thought much better. I haven't seen the 1964 Vincent Price version "The Last Man on Earth" so I can't comment on that one.
