I saw this with Mark at the long-defunct Dendy cinema on George St, the one that used to live inside the Metro, back in 1997 or so. I have seen the sequels since and they are shit (so don't spoil this one by going any further). The underlying design concept, viz a grid of identical sets, would make for a good stage production if there was money enough for serious electromechanical technology.
mrak complained that I write more about movies I hate than those I like. I disagree, I tend to write about the bits that disappoint, having a lifelong hypothesis that the good bits speak for themselves (and speak better than wordy recreations). To step out of character, I'd say this flick is just about perfect for what it is, i.e. shoestring scifi/horror, and the stereotyping of the characters is totally inline with that. Noone's acting skills are taxed here and that's just fine too.
