Inception… My and other takes on Christopher Nolan's Inception can be found at My Posting Career.  Quote:

"What Inception has in common with Nolan's earlier Memento is the theme of mental damage leading to a crisis of identity and awareness. Here of course Nolan is exploring purely amoral aspects of the mind, impulses that the conscious mind is mainly a servant to–complications of our animal evolution and highly developed cerebrum. Nolan's fascination with the mind's workings leads him away from the conscious rationalizations of the moralizer and toward the interrogative analysis of the psychologist."
