Am no stranger to Christopher Nolan - I've seen The Prestige and cried for Hugh Jackman; and I've lost count of how many umpteen times I watched The Dark Knight, each time with the same fascination. So, ahem, my expectations of Inception were huge. I hoped fervently that it wouldn't be an Avatar repeat.
The movie starts out innocently enough; slowly, with each passing frame, it starts sucking you in. What Nolan did was let his imagination run rampant, no bars whatsoever, and then strived to mold that imagination into reality. The end result is nothing short of amazing.

Dom Cobb can extract a person's thoughts from his subconscious. He can enter a person's dream and steal his innermost secrets. He faces the challenge of his life when, instead of extraction, he is required to plant an idea in a person's mind. Inception. A team of expert extractors have to travel therefore, into the subconscious of the subject - go through multiple layers of dreams so they can plant that single thread of thought flawlessly. What follows is a masterpiece of creativity, stunning visuals, and multi-dimensional complexity, the core of which is so simple, it boggles the mind.
I saw Ellen Page for the first time after Juno, and was struck by how young she really is. Cillian Murphy, I've had a mild crush on him since his Red Eye days, and he didn't disappoint. Di Caprio is a master, though I wish he had more of that boyish look from Titanic.
People do not really make what this movie really is; it probably wouldn't have mattered if Nolan cast a bunch of unknown faces - the movie would still be awe-inspiring. It's the kind of psychological thriller that will make you question reality, and re-play scenes of the movie in your mind long after you step out of the theater.
Summing up - edge of the seat narrative, nail-biting pace, and a gripping plot - I can say I got my money's worth, and then some. Go watch it, people.
