To answer that, let me start by writing that if Leonard Maltin would even screen this type of scary flick for his latest guide, he would probably rip into it, just like its man-eating titular character. Tear it apart in a stylized review for many reasons, such as a hokey story, bad music interludes and gratuitous nudity.
Well, not this critic. Instead, I write to applaud its campy moniker, gory effects, solid acting by a couple of actors and its gruesome premise. Unlike Maltin, I enjoy films that could be characterized as B-Movies. Films that would play the second part of any theater's bill. Of course, if they even made it to theaters (similar to this one which debuts on XBOX VOD beginning 8/26 or DVD starting 9/9). Although, to be honest these type of B-movies are often more entertaining and don't take themselves quite so seriously compared to what would be considered a top-billed feature by most critics and movie fans.
And so it goes for "Killer Mermaid". A horror-soaked dive into troubled waters off the Greek coast for two American women vacationing in a Mediterranean paradise. Unfortunately for them (and the other victims that come along for the cruise), a mythical creature resides in the watery depths beneath an isolated island that they decide to visit.
First, they encounter her overzealous protector. A hook-wielding maniac who will murder anyone he thinks will fit the bait to feed her. If that's not enough, then they will have to escape the lure of her captivating siren song and her enclosed fortress lair.
Starring Kristina Klebe ("Proxy") in a strong turn as the heroic girl afraid to swim who must slay the beast to save herself and her friends and legendary Spaghetti Western leading man Franco Nero ("Django") in a small part as a former seaman who knows the dark secrets the seas still keep.
To end this review, I just want to state that I enjoy most of Leonard Maltin's critiques, especially with word that next year will be the last time he publishes another edition. It's just that Maltin clearly has a distaste for these kind of features were I feel that not all films with bad taste can't also be good for you. Or at least, have a higher ranking in his books.
