I can understand how Fulci's style might seem a bit dated now, but it's precisely because of this style that he is so loved for his films. I like Fulci's style, it's quite unlike modern films. I prefer Fulci's style over the hyper-editing that goes on in modern films wherein you can barely make out what's going on because it's been edited by someone overdosing on coke.
So, Fulci - you either take it or leave it, it is what it is, and I have no problem with his style whatsoever. You can't compare old fims with new, because filmmaking is radically different now to how it was back then. You can compare styles, as in how different they are, but you can use neither as a yardstick to gauge good or bad filmmaking. They're simply different.
