Although inevitably linked to the 70's decade, the concept of "exploitation-cinema" is actually nearly as old as cinema itself. Moreover, Universal Studios practically invented the term with their long running monster cycles Dracula, Frankenstein, The Wolf Man and The Mummy. Every original classic spawned a couple of sequels, at least, and after a while they even thought up the idea of making genuine monster stewing! "House of Frankenstein", released one year earlier and also directed by Erle C. Kenton, was quite a successful effort with interesting ideas and enthusiast performances, but "House of Dracula" is a little too loony for me to recommend it. The plot suffers too much from extremely irritating 'coincidental' situations, forced twists & dialogs and – most of all – a far too short running time to elaborate the monsters' personalities like they deserve. Onslow Stevens doesn't receive top billing but plays the most fundamental role as miracle a doctor who's challenged to cure Count Dracula (Carradine) from his incontrollable thirst for blood and fix Lawrence Talbot's illness of mutating into a hairy Wolf Man whenever the moon is full. During a nightly walk in some caves, they also pick up the remainders of Frankenstein's monster and the good doctor himself eventually undergoes a Jekyll/Hyde metamorphosis due to a bad blood transfusion. The last invitation to the messy party is a female hunchback (though not of the Notre Dame). Something is very wrong when you're watching a movie that is literally stuffed with horror icons, yet the only character in the whole movie that is able to freak you out is an ordinary villager going by the name Siegfried. The actual monsters are dull and their once-fabulous backgrounds are fully drained. Count Dracula is a whining romanticist, Talbot is a pitiable and also whining old martyr and the Frankenstein creation … well, his share in the plot isn't even worth mentioning. There's a serious lack of atmospheric settings and nifty photography in this Universal film, especially compared to all their other efforts, and the abrupt climax is a disaster.
