The plot was very thin, although the idea of naked, sexy, man eating sirens is a good one.The film just seemed to meander from one meaningless scene to another with far too few nuddie/splatter/lesbian mouth licking shots in between.The characters were wooden and one dimensional.The ending made no sense.Considering it had Tom Savini and Shaun Hutson in it, you would have expected a decent plot and decent special effects. Some of the effects were quite good but there were just too few of them.Brownie points go for occasional flashes of tits and bush, naturally, and of course the lesbian moments. I also thought that the scene with the sirens bathing in the pool under the waterfall could be viewed as an innovative take on the 'shower scene'The film had many of the elements that go into making a first rate horror film but they were poorly executed or used too sparsely.If I had been watching this alone and aged 15, i would have really enjoyed it for about 10 minutes (with 1 hand of the remote control), then lost interest suddenly and needed a pizza...
