This started very well..who were the 'breathers'..what did they want..and what was the backstory of the family hiding down the shaft.
In the end it turned out the family were Incredible Hulk style creatures with CGI veins! what a let down!
I've seen reviews of this movie that mention "a twist". You might as well just tell us what that is. To tell me and others that there is a twist at the end is the ultimate spoiler, because if you're like me, the entire movie is spent looking for.....yip..... The twist. Classic example being The Sixth Sense. Those fortunate enough to catch that one before the hype didn't see it coming. Those who saw it later worked it out in about 3 minutes. Same with this one. Only here it took me about 3 seconds.
