Sorority girls initiate new members by making them stay in a haunted funhouse. But it turns out there is a real killer on the loose.

On a small island off the California coast it's the Fourth of July and tourists are washing up dead in Babylon Bay, once again! In 1987, rumor has it that mysterious sea creatures called Aquanoids were responsible for 17 vicious deaths. The Mayor dispelled the sightings as urban legend to protect the local tourist trade. Join environmental activist Vanessa DuMont as her fight to save the endangered abalone on Santa Clara Island turns into a fight of her life.

Deadly spiders are accidentally unleashed from a top-secret military installation. Army specialists and Tanks are called in to exterminate the deadly predators, but the outbreak is worse than expected. Weapons of mass destruction have little or no effect on the venomous spiders. Civilians are strangled with spider webs and eaten alive. The Military in a desperate effort to eradicate the killer spiders, decide to demolish the entire city.

Looking uncannily like one of the Fairbrass brothers from camp 90s pop group Right Said Fred, bald psycho Gilbert Gill (Lee Webb) escapes from a mental institution in order to return home and finish the job he started several years earlier: murdering his family! But with his beautiful sister (Perrine Moore, who can't act but certainly knows how to scream) spending the night at a friend's house, how many innocent teens will be slaughtered before Gilbert finally gets to his sexy sibling?
As you can probably tell, originality is not something that this production can boast; neither can it claim to be stylish, slick, professional, well-edited or blessed with a talented cast. However, despite all of these drawbacks, Maniacal actually proves to be quite enjoyable thanks to a genuine sense of fun from everyone involved (who are obviously fans of the slasher genre), some gloriously bad gore, and, of course, plenty of welcome T&A. With these elements in place, it's easy to have a good time with this hokey slice of z-grade horror.
Director Joe Castro handles the film's special effects, but proves to be about as good at providing convincing gore as he is at coaxing credible performances from his actors: the kills in this film are undeniably messy (there are umpteen head-squishes, organ removal, and assorted other nastiness), but they also look incredibly fake (although not quite as fake as the tits on Brooke, the girl in the obligatory shower scene!).
Cheesy, cheap and cheerful, Maniacal offers nothing particularly new to the genre (although the killer's death by Drano was inventive), but at least it doesn't commit the sin of being boring; watch if you're in the mood for some silly low-budget nonsense.
