PARASITIC is truly one of the very worst films I've watched in a while and this is from somebody who watches and enjoys a lot of B-movies so I'm not at all prejudiced against them. However, even by genre standards this is terrible, not even in a good, let's-laugh-along-at-it kind of way. Instead it's an amateur hour production throughout, one of those films where somebody got hold of a camera and thought that was the only qualification they needed to make a film.
The entire film takes place in a single night in a locked-up nightclub. The proprietor eats some tainted sushi in a ridiculous opening scene and after ripping off her top and bra proceeds to turn into a cheesy monster that looks horrible even by genre standards. The rest of the film sees her staff members gradually bumped off one by one as they themselves are infected. Apparently, the proprietor is the only one with the key and the place is locked up tight, all the windows are barred so nobody can get out, and there are no mobile phones to speak of. Yeah, right.
Words can't describe how terrible the quality of the writing is here. I've noticed that this seems to be case when a film shares a writer and director; these guys should stick with the directing because the writing is invariably awful. Tim Martin hasn't got a clue how to write realistic dialogue or how to use it to tell the story. Instead we get endless scenes of characters discussing how they should go and investigate instead of actually doing it. It's padded to the extreme.
The whole film takes place in the dark in order to hide the paucity of the budget and the acting is universally awful, not least from Bianca Holland's bimbo-turned-killer. There's no gore to speak of, hardly any effects, just endless stupidity and characters you hope will die in the most violent ways imaginable; suffice to say they don't. Avoid this trash like the plague.
