An interesting concept, but not enough to carry 2/12 hours, the effects work, the performances are great but as far as I'm concerned they serve to mask (beautifully) a real lack of depth in the script. Still worth seeing but doesn't live up to the hype.

Dicaprio is as ever an excellent lead and the support performances are more than competent, given this and everything else available to Christpher Nolan ($160m to start with) I personally am a little disappointed with the final product, I expected to have felt like I'd experienced something new given the hype, but in the end (other than the wonderful effects) I saw an OK movie hung on an OK premise.
