How bad is it? It's plotless.
Should you see it? It's only for die-hard wrestling fans who also love classic Universal monsters.
In a cemetery, there's a wrestling ring and in it battle Frankenstein's monster, the Wolfman, the Mummy, a zombie, a swamp monster, a witch, a vampire (female), and a Cyclops. Ringside commentary is by former wrestling notables Art Hindle, Jimmy Hart, Kevin Nash, Kelly Coture and Herb Dean. Narration is by Lance Henriksen. There's no explanation, no back story, no conclusion and the fights aren't staged all that well.
