plot holes galore!

There is so much illogic and inconsistency in the script it ruins a powerful concept and what might have been an excellent movie. No doubt the smarties out there will put this off to all the heavy duty symbolism being so all important. Sorry, but first you have to be credible then you can frig about with reality. The ending, to name one, is a complete rip off. To the makers: why sh!t in your own nest? 4/10.
