This movie is absolutely fantastic. So many twists and turns to keep you excited and on the edge of your seat. First things first: I love how it was comical at first before the tragedy hits. So firstly you are clubbing in an underground nightclub and before you know it the world starts shaking, things break and most of your friends are either trapped or dead, you manage to escape just to be chased and tortured by a gang of crazy people.
With maximum blood loss, guts and limbs hanging off I would give this movie a 10/10.
Not for the faint hearted, but if you do love a blender of mixed horror and thriller then this movie is for you.
