One word - brilliant.

Rating: 10/10 (14 November 2010)

I saw this film knowing nothing more than the main cast and if you're reading this for clues on whether or not to spend your hard earned time or money on this flick I recommend, if possible, you do the same. i.e. do not read any other reviews before watching. It really is 10 out of 10. Read on if you want - no spoilers here.
It's not perfect, but what film is? If I was paid to criticise it I could think of a couple minor complaints but within its genre this is as near to perfection as it gets. Other films will be remembered longer and will receive more acclaim but this movie does exactly what it sets out to do better than almost any other I can think of. And the superb cast are all... well, superb.
The first few minutes will enchant you and leave you marvelling at what could possible ensue - and for this reason alone I recommend you see it without learning any more so log off right now and Go see it!!
Why are you still reading??? You're wasting time. Watch it and come back here to write a review - and be sure to put a spoiler caution even if you only mention the genre.
Seeing an enthralling film without knowing anything about it beforehand really is one of life's true pleasures. If only every Sunday afternoon could be like this.
