I suspect it's mainly down to the appalling acting skills of many of the cast, who seem to think that shouting (and in one case, screeching) nearly every line of dialogue is a good substitute for emotion?
However, there are quieter moments when some semblance of nuance shines through, and the sets and lighting can be quite good at times, and there's a relatively interesting story lurking under it all.
It's hard to critique something that was never finished but, given much of the footage here, one suspects that a late injection of cash would have been used just to complete the story, rather than returning to start again on some of the worst bits.
Not recommended, really.
