Mark my word: Inception will be considered a groundbreaking pioneer in storytelling for many years to come. The more I think and the more I read about it, the more I am baffled at how many profound levels it works on the concept of dreams, stories, cinema, reality, emotions, the human mind, and life. That's why comparing it to The Matrix would probably be a disservice to it. Even pointing out the subjects mentioned would be impossible in a 100-word review, so I'll leave any discussion up to you. Comment away, and I'll post my opinion on whatever you please.
PS: This great review may act as a good discussion starter. Watch out - huge spoilers.
