Deserves less than a zero! Nolan should do some research first.

Rating: 1/10 (11 August 2010)

The movie is a cascade of factual errors and logical errors. The very foundation of the movie is so totally wrong and mistaken, that the movie makes no sense at all.
Nolan should have done some research on "Lucid Dreaming" to get his facts straight. Reading only one book would have sufficed (Lucid Dreaming, by Steven Laberge).
Were other movies brilliantly succeed (Dreamscape, Matrix, Existenz and possibly others), Inception miserably fails...
For people who know very little about dreaming, this movie may seem great, but for those who do, this movie is a joke. Really too bad, I just can't understand how writers / directors can totally ruin potentially great ideas and concepts.
