Also vampires, werewolves, Frankenstein's Monster, the Brides of Dracula, Mr. Jeckyll and Doctor Hyde, a secret religious order with steampunk antivampire Bond gadgets, an excellent soundtrack, decent production quality, and some surprisingly good performances with just the right amount of scenery chewing (which in the case of the actor who plays Dracula is AS MUCH AS IS HUMANLY POSSIBLE). To my mind it neatly hits the sweet spot where there's just the right amount of ludicrousness to be fun but which is then played completely straight, so it doesn't quite cross the border into camp. The result is something which I find enormously entertaining. I suspect that leads had a lot of fun making this. Bear in mind it did get 23% on Rotten Tomatoes, so YMMV. (Obviously everybody except me must be wrong.)
