I was in high school the last time I saw Lucio Fulci's Zombie (1979) in one sitting. I've seen bits of it in the years since. Its most outré sequences show up in the culture outside the context of the film. I mean, an ad for a satellite service borrowed the film's notorious "zombie vs. shark" sequence a few years back and nobody blinked. It's a sad comedown for one of the original video nasties.
In truth, I've never revisited it because back when I was a young whippersnapper, I didn't really like it even if it did tickle something in the gorehound I used to be. I admit that the version I watched with my friends all those years ago was less than ideal: it was a dub off of some fly by night TV channel. I don't remember its exact provenance. It wasn't a commercial dub because it was grainy and cropped and not even panned and scanned. It must have come off of cable because it had its nudity intact, to say nothing of its zombie cannibal feasts. It certainly delivered on the gore. THAT, at least, I remember with vivid clarity. The story? Well, that's another matter. Like many Italian horror films of similar vintage, I thought the stuff between the set pieces was boring.
