Dude, the DVD just arrive here and I went to home to watch it:

It's just amazing, marvelous, wonderful, and any other thing you would call it.
Bedes to be italian, all movie has a great story, that have been copied till the hell, and some scenes that today it's hard to see on horror movies.
The scene when Susan is under water and meets the zombie, who fight with (guess what?) A SHARK! HHAHAHAHAHA
And it's a damn real shark, and why not to say the big ones???
This freak zombie lost his left arm, eaten by the shark, and still gave him some BITES!
OH DEAR LORD! HE bite a SHARK!!

Many other scenes are impreve, like in dr. Menard house, where his wife is killed by a zombie that pierce her eyes. What a scene!

The movie has a great story, as I said, and good actors too (specially the walking zombies). They just made some mistakes, but nothing that blur the film.
The make-up effects of the deaths and zombies are pretty good for a 70s film.
Much blood, maggotts and more ck things are shown in this great film.
Recommended for zombie fans!
