I use to be really big into Romero's dead series. My favorite of the series remains "Day Of the Dead". But these days as I got back and view these films, I see just how badly directed they are.
NOW, I just watched "The Last Man On Earth" with Vincent Price (which came before NOTLD) nd I just couldn't help but to think how Romero basically ripped off this film. If you think Romero's take on zombies is original, check out the Vincent Price film.
