What if someone took some of the ideas and feel of The Matrix, added a better story, made it far more complex, 10 times smarter, and with better acting and underlying feel?
That someone was Christpher Nolan, and this is that movie. A must see that combines action, philosophy, lost love, dreams, the power of ideas, and time dilation all in 2 1/2 hours of stunning visuals.
The movie centers around a small group of theives that use a technology that allows people to enter a shared dream state with a target victim who doesn't know they're dreaming. Essentially a heist sci-fi movie, built on a backbone of existential philosophy.
I doubt anyone could have pulled this off but Christpher Nolan, who wrote and directed this movie, and developed it slowly over the course of 9 or 10 years.
