The opening is sick as hell. Shame about the rest.
Forget "The Dark Knight". Forget "The Dark Knight Rises". Forget even "Inception". This film matches the levels of greatness that "Memento", my favorite Nolan film, manages to reach, and it does it without telling the story backwards. This is dark, mysterious, captivating, intelligent, and is easily one of Nolan's most under rated films so far.
