Boris Karloff makes his final appearance as the Frankenstein Monster in this zippy little classic where Dr. Frankenstein’s son (Basil Rathbone) sets out to clear his dead father’s name as the creator of a murdering monster and restore his reputation as a brilliant scientist. So he finds The Monster and electric-shocks him back to health, intending for the beast to be studied for the cause of benign scientific advancement, but what the hell kind of movie would that make? Of course, Karloff goes crazy again and rampages the countryside. It’s good stuff, but this also marks the point where the Universal monster movies become more episodic affairs, sliding into B-movies after this. Among the notable good performances come from Lionel Atwill as a police inspector with a false arm—his limb ripped from the socket years ago by The Monster—and Bela Lugosi as Ygor, Frankenstein Sr.’s old mongoloid graverobbing assistant who still putters about the village scaring people and plotting against old enemies.
