What Causes Zombies? . A sailboat arrives in New York Harbor.  It seems abandoned but a coast guard member is killed by a man on board.  The man is shot and falls into the harbor.  The boat belongs to a man whose daughter is concerned about him.  She and a reporter hire a boat to find her father.  Their destination is an island said to be cursed.  The boat they hire is run by a young couple.  Along the way the couple do some diving (she is topless).  She is scared when she sees a man under the water who attacks a shark and tries to eat it.  She is very upset and somehow loses the rest of her suit when removing her tanks.  The Continue to the island which is just a short distance away.    Once on the island they discover researchers looking into a phenomena where the dead rise to attack the living.  Legend says it is the work of voodoo but the lead scientist is convinced there is a medical explanation.  Unfortunately the missing father has already died but at least now it is known.  But soon the zombie trouble gets out of control as cemeteries give up hordes of the walking dead.  In the end, only a few manage to escape the island to head back to civilization.  They keep one zombie as proof that they are not crazy.    This is one of the better zombie films although the final battle is a little odd as zombies seem to appear out of nowhere inside buildings.  That aside the story builds nicely with the multiple plots weaving together smoothly.  There is plenty of nudity in this one and plenty of gore, although somewhat tame by today's standards.  The acting is reasonable for the effort and special effects are decent.  I enjoyed the ending which I gather was supposed to be a shocker but which I predicted from the beginning.  My guess is that most viewers will get too caught up in the rest of the movie to think that far ahead, or so the producers hoped.  If you like zombie films you will have to check this one out

SUCKS. . Garbage. They tweaked it in every place that didn't need tweaking. Straker is no longer bald, Matt Burke is no longer caucasion, and now he's gay. The bus driver is now a vietnam vet instead of korea. In this adaptation, Ben Mears was the kid who found the bodies of Hubie Marsten and his wife. The story begins in winter instead of late summer. Ralphie Glick doesn't just go missing, he's drowned in an icey pond. Instead of Ben Mears coming to town and finding the Marsten house already sold, Crockett has already promised it to Mears, but now he's renegged and sold it out from under him. I don't see the point. They didn't just change the story, they didn't leave anything intact. It's bad. It's unwatchable, especially if you loved the book. None of the characters have Maine accents... Hmm. Could it have been filmed in... oh I dunno... AUSTRALIA PERHAPS?
