For a moment there I thought the 4 Xs were implying "Porn of the dead". But I have to agree, the earlier films are great. They're B-movie-ish, which I like in a horror movie. In a strange way, it makes it more believable. In some big budget horrors recently, like the Exorcism of what'sherface, I just can't get into the movie because I think: "Oo, nice/crap effects"
