Although it is a thrilling film in parts, somewhat sagging, it was woefully let down by the incredible and bizarre stupidity of the characters.

If everyone was rational the film would have ended in 10 minutes, but no absurdity had to get a look in.

I loved the non linear story telling. Your mind is taken through a tense drama of cat and mouse, and then back and forth with different chapters, filling in more detail as you build a picture of whole drama.

But, a big but, and this is why everyone complains the golden age of cinema is well and truly over. To make the story work the film needed a tonne of stupidity and suspension of disbelief. This lets the film down badly to the extent you leave the cinema thinking it was all rubbish.

I think the film will end up at 6.7 (it started off at 8 and at the time of writing it had fallen to 7.1). Another wannabe-clever film, soon to be forgotten.
