The Revenge of The Living Dead Girls (1987) a.k.a La Revanche Des Mortes Vivantes

  A small town's milk supply is contaminated with a deadly chemical causing the death of three girls. The chemical company responsible for the chemical tries to get rid of the waste and gives the job to a local guy who dumps it in the local cemetery. The chemical brings the three dead girls back to life and they are out for revenge!
  Pierre B. Reinhard, a master of French and European sleaze, directs this masterpiece often celebrated as the first French gore horror film. A story worth of the film's title, amazing sets, lots of nudity (it's a French film so it makes sense) and a bulk of well portrayed gore! It may seem too sleazy and cheap for a film of its genre but it certainly pays off. Plus, that cheap-looking European glowy color in the film's photography is over the top and brings another air in the zombie genre! Total decadence!
  Acting is not a huge deal here. Female actors are either nude, having sex or dead (hue hue!) while the male ones try to much to be the macho type. Surprisingly, the zombie women move quite good for zombies making realistic enough to set aside the negatives!
Must watch this : on a cold November night or on Halloween, with a glass of milk (get it?!). After the film, try and convince a girl friend to let you bury her in the woods and shoot photographs. Of course, she has to be naked!
