I think my biggest issue with this film was, to me, the dreams weren't very realistic. In a sense that, when I dream, they're nothing like it is depicted in the film. This annoyed me! The dream sequences are very Hollywood stylized.

Don't get my wrong, the acting in this film is superb, with names like Leo Decaprio & Joseph Gordan of course it would be. The special effects are also quite incredible.

If you want to watch something that, in my opinion, realistically depicts how we actually dream. Give Joss Wheadon's take on it a look. Its spot on in Buffy The Vampire Slayer - Season 4, Episode 22 : Restess.

I gave it a 6 as it is a well written and well executed film. Great if you want to watch something that will make you think long after.
