With all the marquees lit up with mostly hack remakes and unoriginal ideas these days, Inception stands out as a satisfying gem.
It is, at it's core, a sci-fi thriller that hits the same notes and beats as TV's "Lost", minus the stretched out and over-wrought mythology. Most of the action occurs in a dreamscape that doesn't seem so dreamlike, so the viewer doesn't get too lost in the fantasy. There are rules, and there are layers, but it's not too hard to keep track due to deft explanation. It's fun and thought provoking.
The depth of storytelling harkens back to Christopher Nolan's "Following", with even some noir flourishes at times. Nolan is definitely at the top of his game here.
Overall, it's a great cerebral flick that will captivate. It relies on a little bit of patient attention from the viewer early on as the rules are laid out, but then a switch is flipped and the action kicks in. If you're looking for a mindless romp, stay away. But if you're looking for one of the most original ideas to hit the big screen since Fight Club or The Matrix, it's a must-see.
