The film's great, blah blah, nothing new.
This is really to comment on the Blu-Ray variable aspect ratio that is featured on this BD. As a film purist, I was VERY sceptical about the idea of moving from letterbox to full-screen aspect ratios during such a brilliant film. I was so worried that it would look cheap and gimmicky that I rented the BD before buying to make up my mind. At the worst, I would get the DVD and get the whole thing in letterbox format, I thought.
Looking back, I am glad I checked, because it really could have been awful, but honestly? I'm not sure how I could imagine that such a landmark film would be the object of cheap gimmicks...
The switching from letterbox to full screen is so subtly integrated that my wife didn't even notice it(and she's just as film savvy as I am - I knew about the VAR so I was looking out for the switches)
Here's the verdict: I found that it actually added to the film.
The opening bank heist and the lorry vs bike scene (don't pretend you don't know the one...) both get the full screen treatment. Obviously, they are two amazing set pieces that really benefit from the involving appeal of the full-screen experience. They are also two scenes that must have been intentionally shot with no important info on the sides, so you really do lose nothing you would have wanted to keep and you gain immersion and pixel-perfect definition. This is not Channel 5 cutting of the sides of your favourite movies just to get rid of the black stripes. When the black stripes go, it's because it really is best that way. And then when they come back, it's integrated into dark scenes so that you don't even realise it.
Other full-screen moments include wide-angle pans over the city giving you a completely immersive experience. The switch to full-screen on these scenes give you the impression of flying over Gotham at night. Incredible.
I will now never accept to see the film in any other format. This truly seems to be the director's vision. And if it isn't, then it should be. Who would have thought that The Dark Knight could be improved on? I feel humbled.
EDIT: Yes, obviously, when I say full screen, I mean the full 16:9 (1.78:1) of an HD TV, as opposed to letter-box 2.4:1 which presents black lines at the top and bottom of the screen. (For those commentators who appear to be watching their blu-ray films on a 4:3 cathode-ray tube... I do suggest sticking to DVD or even VHS: it's much cheaper! Another tip would be to buy two speakers so you can upgrade to stereo sound! I hope this clarifies things for you.)
Though it is interesting to learn that the sequences that I was so impressed with were originally shot with that 16:9 IMAX ratio, staying therefore 100% true to the director's vision. So in the end it's the DVD version that cuts material off, not this blu-ray version. Thanks for the info!
