If you think you would enjoy two hours of people shouting and swearing at each other in the dark, by all means see this movie. Silly, dreadful, unrealistic, absurd, pointless and confusing. I wasn't really sure what it was all about until after I looked it up on IMDb. Oh...it was a horror flick... No it wasn't, it was a disaster flick. In any case it was disastrously horrible. It begins with a bring your kid to work scenario except the kid is a sexpot adult woman and work is a coal mine. Something gives way or explodes or collapses --- thats never made clear --- and this unlikely group find themselves trapped underground. Rather than wait for promised rescue in 72 hours, they decide to explore. Booogie Boogie Boogie!!! At that point I wasn't sure who the bad guy was or why. Or was it possibly a bad gal? Or maybe a bad ghost? But it certainly was a bad movie!
