"Inception" is certainly the cinematic equivalent to a roller coaster ride. It also features unique, creative imagery, and an equally creative premise: a company has created a technology to intrude dreams to manipulate thoughts. They can insert hired dreamers into one person's dream, ideally with the intruders knowing they're on a job and the target dreamer being unaware that he is being manipulated.

To make things even more complicated, dreamers can dream within dreams, and things happen faster in dreams than in reality. And "inserters" can create places and settings and adopt different appearances. This makes the setup pretty complicated to understand -- you probably won't get it all in the first viewing. To aggravate matters, the rest of the plot is long and winding like the Chinese wall, and action-packed like a He-Man episode.

I'd call this a big-explosions blockbuster with brains. Personally I wasn't able to fully buy the premise -- for all the action, I didn't see how burglaring a dream could lead to change one person's thoughts, so I wasn't able to sit back and enjoy it as much as I'd have liked to.
