This is an odd one. Although the story is a little short on logic, it stands on its own due to the gory effects, which are sometimes extremely bloody. As with all the Italian-made films, the acting is not very good, and the camera is sometimes amateurish, but it compensates with plenty of gore, good cavern sets and a good score, not to mention the tag line, which is either going to make you frown or laugh.
