The essential problem with this movie is that it has no logic rules to abide by. And, mind you, even dreams have rules, as Freud started to hint. A rule is not "I do what pleases me", which is what we see throughout this movie. That's arbitrariness. Mr. Nolan should learn from hard working writers to build seriously an imaginary universe, like Tolkien, Borges, Frank Herbert, etc. Worlds with RULES. Because without rules, the writer can do whatever pleases him any moment. And as anything is possible,... who cares? And as one stops caring, one starts to get booooooored. Specially if in a supposedly imaginative story you get punished endlessly with the oh-so-hackneyed pursuits and shoot-out of faceless bad guys... Yah, yeah, yeah, original, new and unseen as an Edwin S. Porter film. Yaaaaaaaaaaaaaaaaaaaaaaaaaawnie!
