It is an true art form to make a good parody, an art form that Mel Brooks perfected. And even if Mel Brooks has a brief cameo, it is Ezio Greggio that is the mastermind of this one. And though he don't reach the heights of Brooks, he and the rest of the cast and crew delivers a good parody. The base for the parody is Silence of the Lambs and Psycho, but some other movies get spoofed along the way.
In a movie as this it is the jokes that is the essence of it all. One can't really talk of a coherent plot nor is the cast performance the major part. Note however that the performance is not bad, but it is more fun to try to recognize each actor/actress instead, as it is used in some jokes. Now, the joke part, I think that the major part of the jokes and spoofs was very funny. Some didn't work, and some too predictable to produce much laughter. However, all in all, the jokes were good and well worth the time spent watching the movie.
