Let me come straight to the point with this one and admit that "Mad Monster Party?" nearly wasn't as good or as much fun as I hoped it would be. The actual plot is rather weak, the film is overlong, a large amount of the gags entirely miss their effect and there's way too much singing and dancing going on. What the hell was that about? Someone really ought to add the tag "musical" to the genre description here on the film's IMDb page! But on the other hand, I can't possibly be too harsh or overly critical about a movie that pays so much tribute to my all-time favorite genre of cinema and all of its legendary contributors! All minor defaults and shortcomings aside, "Mad Monster Party?" is a warm-spirited, enthusiast and freshly inventive ode to (classic) horror from the 1930's to the 1960's. As a European kid born in the 80's, I'm not too familiar with the works of Arthur Rankin and Jules Bass, and I never watched any of the "Frosty the Snowman" or "Rudolf the Red-Nose Reindeer" cartoons as child. But the simple fact that these men managed to cast the awesome Boris Karloff himself in order to voice the Baron Von Frankenstein pivot character more than enough proves to me that they know and respect a great deal of the horror genre. Up in the tower of his castle on the remote Isle of Evil, Baron Von Frankenstein just finished his latest and greatest invention; an all-destructive liquid in a tube! In order to celebrate his invention, and primarily also to make an important announcement, he invites all of his monster friends over to the island. And oh yes, all the protagonists from the brilliant horror milestones (Universal and others) attend the monster mash: Count Dracula, the Wolf Man, the Hunchback of Notre Dame, Frankenstein's creature and his bride, the Mummy, The Invisible Man, the Creature from Black Lagoon, Dr. Jekyll and Mr. Hyde and an uninvited mystery guest referred to as "it". However, the party turns sour and hostile when the monsters learn that Baron Von Frankenstein will announce his retirement and that he will hand over all of his secret formulas to a nerdy outsider – his nephew – instead of to one of them. The newly added character of Francesca, the Baron's voluptuous and sly secretary, is still original, but other side-characters like butler Yetch (with a voice reminiscent of Peter Lorre), Chef Machiavelli and even Felix Flanken are quite redundant. Instead of giving lines and lyrics to them, I personally would have much preferred that the parts of the familiar monster favorites were a bit more extended. Most of them don't have anything to do, except to howl and groan occasionally. The Claymation is inarguably wonderful and still very admirable even by today's high standards. I bet that even nowadays clay-wizards like Adam Elliot ("Mary and Max") or Peter Lord ("Wallace & Gromit") are big fans of these designs and that they couldn't do a better job.
