However, it's just a boring story that steals heavily from Frankenstein (1931) and about a hundred other films as well. I watched it to the horribly moralizing ending and could only muster a "Who cares?" Even though the bodies hit the floor at regular intervals, there is almost no blood or horror elements to be found. Furthermore, there wasn't enough suspense to qualify it as a thriller either.
I never need to see this one again. Spare yourself the agonizing 97 minutes and watch one of the other films made by these two wonderful actors. Ugh!
