There is not much to say about this series of film that hasn't already been said: it's a cheap, commercial slasher movie that uses way too much Ludicrous Gibs
to even be "entertaining".
It's just a Doom-like
videogame without the guns and the undead. The plot is trite, the deaths are predictable and nothing short of overdone, the characters are flat as shit and the ending isn't even satisfying. It's a pointless Excuse Plot
used to show people getting chopped up and butchered in every imaginable way. But this alone doesn't make a great show.
This kind of movie is done only to attract slasher movie enthusiasts and people in need of a good scare. But, unless Ludicrous Gibs
are enough to fascinate you, there is nothing of note there. It's just another of those works people watch/read to satisy their voyeurism and to try and tame their visceral fear of death by watching atrocities.
