That movie has been produced and directed by the same people, who enriched the world of cinema with such masterpieces, as Troll 2, The Crawlers... Well, although this movie is not THAT horrible and ridiculous, as Troll 2 and Crawlers, although special effects (done by the same italian "Greg Cannom" (Mrs. Doubtfire, Bram Stocker´s Dracula, Titanic, etc.) Maurizio Trani, who have done some poor FX for Troll 2 and Crawlers, this movie stinks anyway. It´s a low-budget hilarity, where the characters behave as nobody would in real life. It also contains some episodes from the first part of this masterpiece (Casa 3, or Ghosthouse (1987), and which is in no way better. All these four movies were produced by an ultra low-budget company Filmirage. By the way, they had used the SAME score in Crawlers and in Witchery! What a shame!
