Ehh, this is not exactly a movie. It's a four chapter t.v. mini series. Still, I watched it on a classic movie channel from Mexican cable and it was featured as a complete movie. You see, they didn't separate the chapters and made a single movie.
The dialogs are the best feature about this one. You see, according to the script, we are in front of a master evil mind that should terrorize Frankenstein!
Sadly, the lack of suspense and action makes this a forgettable effort. Joaquin Cordero was the best feature about it. The man is a great actor.
Still, I strongly recommend you not to seek after this title. It gets odd and boring pretty fast. Watch it only on cable or if your hunger for b-classical entertainment is ferox.
