It's necessary to have one's mind "ready" before watching "Inception," otherwise it will be easy to get lost in this labyrinth's layers of storytelling. The movie is maybe over-thought and sometimes too complicated to understand and follow, however the challenging material is quite satisfying. Nolan puts intentionally the viewers off balance from the beginning of the story. As a result the audience has the impression of being in the middle of the film, of living it personally. There are ideas comprehensible (though not easy to understand) but overall the reality depicted in the picture must be interpreted in order to get to follow everything. The visual effects are stunning and maybe the best ones ever seen to date, Di Caprio and Murphy both show great depth of character, so if you're willing to stay for a long time and endure all these complications the film may work.
