You can count me among the truly unimpressed.  Having read reviews and heard lots of good things about this, I saw it the other day with considerable anticipation.

Heath Ledger is very good, but the rest of the cast.....

Gary Oldman turns in the worst performance I've ever seen him do in a generally fine career.

Morgan Freeman is just the same character he's played in twenty other movies, only more sanctimonious.

Christian Bale is competent, but generally uncompelling.

Michael Caine acts like he's needing a downpayment for the nursing home.

The movie starts strong, with a great action sequence bank robbery, but quickly bogs down in a pretentious, overly preachy examination of the psyche of Batman. Which is all well and good, except it didn't need to be done at least five separate times, with no discernable advance of the theme or plot.

The action sequences pick up in intensity, but devolve into ever increasing use of CGI which made me feel like I was watching a video game and not a movie.

The film really needs an editor. At least 30 minutes of repetitive and redundant dialogue or pointless scenes could have been cut to the greater benefit of the film. There is far too much pretentious pseudo-philosophy, all of which is signalled by dramatic musical fanfares.

The internal logic of the film is ludicrous. Let me be clear. I'm prepared to suspend disbelief in a movie, and I'm doubly prepared to suspend it in a superhero movie, but the internal logic has to work, at least basically. There are at least 4 major points when it doesn't.

On the upside, Ledger's performance is very good, far better than anything I've seen in this kind of film. (Unfortunately, we all know he won't be reprising it.) In addition the film is dark and more adult oriented than is common in this kind of film, which I regard as a plus.
