It's difficult to give a review on this film without giving bits away.
Suffice to say, it's atmospheric, with some great cinematography. It is set in some post apocalypse era, but we don't know what happened. It is brutal, with graphic sex scenes and good acting. None of the characters are particularly loveable, as they are all pretty paranoid and are clearly used to committing brutal acts at the drop of a hat in order to stay alive. It captures the darkness of the situation perfectly. I could almost describe it as a horror film, if it went one step further, or introduced some gremlins etc....
It is not for everyone and definitely not for kids.
I really enjoyed it!
