『记忆碎片』is one type of movie

in my opinion, in which "truth" just hide from you through whole story by presenting the story in a very unique way. You see pieces of story flying around. Have to take some time to figur out what actually happened, in what sequence and then may understand a little about what story is trying to tell you.

Recently I found I am not the only stupid guy that have to see several times to understand a little better.  Many still claim not having any clues.....

Thought Nolan is kind of crazy guy.
