I'm not sure that a four-star rating does this movie justice: the killer, the storyline, the ending and the inventive death scenes were all worth the full five - but the gore in this movie is very eddited. The way in which the killer murders the victims is gruesome and cleaver...but the scene of murder ends before any of the real gore starts. If the movie had not been so cut, it would have been fantastic instead of just very good; this is why I have only given it four stars.
However, dont let that put you off, this movie is creepy and suspenceful and it actually features a pretty cool killer. It is still a very good movie and does feature moderate amounts of gore - as long as you aren't expecting buckets of blood this movie will not dissappoint.
On Valentines Day 1960, the men in charge of running the mines left early to attend a valentines party, leaving the workers down in the mines without checking the levels of methane gas in the air. The gas levels rose too high causing a minor explosion and the mines partially collapsed, leaving only one survivor, Harry Warden, who then went crazy and murdered the three people who had left without checking the methane levels. He was then admitted into a mental institution.
