Inception

Not a dream but the movie I would recomend (one I have seen twice). In some ways I think it is 'The Matrix' of this decade, though I would rather watch Leonardo DiCaprio on film than Keanu Reeves any day. While it has been criticized - and I can agree somewhat - for drowning an intriguing premise with too many gratuitous gunfights (Inception, not the Matrix) for me the intrigue remains, well, intriguing, as the characters grapple with being in a dream within a dream within a dream...and so on. It leaves you questioning whether 'the real world' in the film is in fact real at all, something which stuck with me as I left the cinema and had me pondering the reality of the world around me for a while.
