Smart, quirky, funny. Wonderful production design.
Not sure about much more to say - only I was amused by this quote on IMDB:
Before the shooting began, Christopher Nolan invited the whole film crew to a private screening of Blade Runner (1982). After the film he said to the whole crew, "This is how we're going to make Batman."
No wonder I liked the look. And I want a Batmobile.
