Strange light when there is no electricity quickly leads to the classic, have sex and die scene. Soon there is running and screaming and a car that has flats and does not start. The tired going back into the creepy dark building, then more running and dying. The mystery was a bit interesting and seeing Paul Naschy as the evil security guard was cool. Overall though this is pretty standard stuff and for all their talk of knowing horror movies the characters in this one made the same mistakes.
The movie looks dark, and the sound and music was a bit grating.
