I'll admit to only having seen this once, and it being many years ago. I'd have to watch it again to really appreciate it in any kind of artistic sense.. Though, i agree that it just won't match to the Romero classics, even if it is unofficially classified as a prequel. Not to mention the fact that there are like 5 sequels to this film. I've been tempted to buy a 3 pack at BestBuy for like $20 bucks of Zombie 3, 4, and 5, but have a feeling i might be dissapointed..
Much like i was with the film "The Beyond", another Lucio Fulci "zombie classic".. While it wasn't an altogether horrible film, and was surely influential to other film makers, i just personally didn't find it as appealing as other classic 70's horror films such as PHANTASM (The Beyond was actually made in 1981, 3-4 years prior of Romero's 'Day of the Dead)
Again, i can see the allure of Dario Argento, Fulci and many other film-makers, but people like Romero, or Sam Raimi, Tobe Hooper, usually "out-scare" the films made in Europe and Italy, at least IMO... U-S-A, U-S-A, U-S-A...!!!

I'm sure that budget might play into this though.. But Night of the Living Dead, Texas Chainsaw Massacre and Evil Dead have some of the smallest budgets of any cult classic horror films every produced...
