This movie is about dreams in a sense that the main characters have the ability to dream on demand, and enter other peoples' dreams. I have always been fascinated by dreams; the difference in the perception of time in dream space; the effects of the physical changes occurring in the dreamer's reality to the events in his or her dream.

I was excited towards the beginning of the film where the main characters are shown to explore and build dream worlds. The plot which follows is too complicated to be enjoyed. It is a pretty good plot with very few loose ends, but I felt that the filmmakers could have made a more fantastic a more rich experience when it comes to the dream worlds shown in the film.

I would rate Shutter Island, which is similar in the sense that it deals with the imaginative powers of the mind and its effects, a lot higher. Or a film like Eternal Sunshine of the Spotless Mind, where thoughts and memories and the wanderings of the mind are depicted in so touching a manner.

Inception has gunmen and hand grenade launchers, fast car chases and action...things which were not completely necessary for the plot to seem effective. I felt that the film could have made use of the creative license that dreams gives it, in a far more effective way.

Also, Dreaming Is a Private Thing. Sharing dreams is a definite no no :). http://en.wikipedia.org/wiki/Dreaming_Is_a_Private_Thing
