Frankenstein's Bloody Terror ★½

I admire the chutzpah it takes to acquire a Spanish werewolf/vampire movie, slap a Frankenstein title on it, and sell it in place of (the unwatchable) Dracula Vs. Frankenstein you originally promised to American theaters, which is what distributor Sam Sherman did in the early 1970s with Frankenstein’s Bloody Terror. The movie is terrible, but at least it introduced me to Paul Naschy, who is apparently Spain’s barrel-chested Boris Karloff.
