Underground

Some of the comments here are just a tad bit too good for this movie, as it really does suck and will bore anyone out of their mind, if not get him quite mad because it lacks the basic logic also! You could say that indeed it is some sort of breed between The Descent and The Cave, probably & Creep also, but I think that Underground only got the bad parts from them.

Seriously, this is one of them very bad movies, even the camera work is terrible, as you will see it shaking from time to time, the characters are not so bad OK, but the plot, well we really have a problem here! Cheesy cheesy, cliché, cliché and you can always tell when someone else is going to die! As for the creatures, when you'll hear the explanation for them, you'll probably start laughing, only good part of the movie to be honest.

Bottom line, do try The Descent, The Cave, Creep even Stag Night, but stay awaaaaay from this one! I gave it a 3! Solid 3!
