Are the dreams portrayed in Inception anything like yours? Of course not. The movie's dreams aren't like anyone's and that's not the point of the movie. The style of director Christopher Nolan's Memento doesn't correctly mimic that of a man with short-term memory loss, either. It's only a style necessary to pull off an effect and that's the purpose of the style of the dreams in Inception; it's only a plot device and not intended to accurately recreate the sensation of dreaming. Nolan takes elements of dreams to further his plot - a roller coaster ride of what's essentially a one-last-heist plot - and that's all but that's enough.
Nolan barely mis-steps through his movie, hitting the buttons he needs to keep things moving along in a grand, entertaining manner. For the first time, I actually liked Leonardo DiCaprio and Joseph Gordon-Levitt plays a strong second but Nolan erred by casting Ellen Page as the ingenue. I still have her roles in Juno and Whip It stuck in my head so I still see her as the 17 year old she was in those movies instead of what I presume to be her 23 year old role here. Jarring but not overwhelmingly so. Nolan ends with the movie with sly twist, wrapping up what was for me a very satisfying movie experience.
