As they explore deeper and deeper into the caves one of the girls slips down a slope and we get to see one the most disgusting injuries known to man (or woman), the compound fracture. Maybe it’s just me but seeing bones protruding through your flesh is just not right. Anytime this happens in a movie you know they are so done for, this was no exception. The bad news continues to mount when they start seeing things. This is our introduction to the Crawlers. These possibly former humans have evolved and adapted to suit their environment. They are completely blind but have heightened sound and smell. The action between the women and the crawlers is intense and frenetic. This crazy action has its consequences when one of the girls mistakenly kills another. What makes this film so scary is the fact that the crawlers are blind. In many instances, the women are face to face with them or hiding just inches away. The women get split up and despite their best efforts start to die off. Our main character Sarah turns into a modern incarnation of Sarah Connor from T2. She is quite the crawler killing badass.
Like I mentioned in the beginning, the ending has two different versions. The U.S. version has Sarah escaping from the caves and driving off. While the U.K. version adds another scene on top of that making it a much ominous ending. U.S. audiences prefer happy endings, hey who doesn’t. The Brits I guess.
