This ultra-cheap Thai export, borrows wholesale from the last third of "Jaws", and yet despite the carbon copy approach, manages to end without the audience even knowing if the title beast has been overcome, or whether the hero has survived. There's an almighty commotion, then, the film abruptly ends.
While enjoying a weekend getaway with their wives and offspring, Dr. Tony and his budding medic friend soon become widows of an oceanic behemoth, that proceeds to devour everything in its path. Not content to grieve in silence, the pair gesticulate for about three-quarters of an hour on how they'll avenge their family's deaths; meanwhile, the beast is causing mayhem in the local village. After much soul-searching, reflection and the occasional bizarre chemistry experiment, the two eventually enlist the services of a rugged fisherman Tanaka (Kirk Warren) and set off by boat to end the creature's path of chaos and destruction.
Frequent use of miniature sets and paltry special effects afford this film a corny quality the antithesis of the otherwise intense and heavy-handedness of the characterisations. Disjointed editing, unintelligible dubbing, droning monotone synthesisers, and annoying cinematography (from extreme darkness to blinding sunlight pans) don't assist the flailing storyline. Must surely be considered a curiosity, and will more than likely compel a second look, even if just to try and decipher what happened (or didn't happen, but should have). An interesting insight into late 70's Thai cinema, and the techniques that were unemployed when making movies.
