Terrifying and realistic opening, squeezing through dark and unknown caves deep underground.

Rating: 6/10 (1 November 2015)

Initially started out as a great movie, was suitably horrifying as you watched the women squeeze through tight and restrictive tunnels with no known exit and sheer drops. Felt realistically scary, who isn't scared at the idea of getting stuck in a tunnel or cave with no escape? Then they discover they aren't alone and it goes downhill as they are chased by what basically looks like the hand me down costumes of Orcs from Lord of the Rings. It's one of those times that once you see the 'creatures' it stops being scary and look stupid instead. I think it would of been scarier if these creatures were more human like, the idea of abandoned cavers adapting and turning savage is better then silly and overdone inbred looking goblins.
