Dogs are definitely a running theme. More on this is a minute.
Another dog reference - "when the chips are down, they'll turn on each other like dogs..."
So the Dark Knight and the Joker are both hunters, both fighters... A book I've read about dog training points out that when you look up dogged in the dictionary, it means stubborn - that fits dogs and our two main characters.
I was really struck by the opposite reaction. The movie is such a moving comic book - the framing, the shot choices, the dialogue (which is sometimes a little painfully "Comic Book"). I think a lot of comics fans found Harvey's transformation a little jarring because we're waiting for it from his first scene, which includes the coin - but the use of him in this story is pretty far removed from his traditional role in Batman stories; except that it's not - he's still a doppleganger for Batman, but moreso as Harvey than as Two-Face. That's what's unusual.
I guess I hadn't really bought the coin conceit as it was presented. I was perfectly ready to see Harvey start killing people at that point in the movie, but I didn't see where his compulsion to give in to his better half might come from, or why he'd leave it up to a coin toss. That struck me as sacrificing characterization for the sake of including the character trait from the books. For Harvey to let the Joker go because of a coin toss...?
Actually every bit of the Swat teams' entrapment by the lines is right there on camera. It just happens quickly. I actually like that this stuff is a little confusing during a first viewing - it gives you something to uncover with subsequent viewings. And the detail is impressive.
I'll have to trust you on this - only seen it once, and it went by in a (dark) flash. It certainly all looked accidental. It would have been an interesting parallel to draw, that both the Joker and Batman plan three or four steps ahead of ordinary people. (but on my viewing, in that scene, he just looked ridiculously lucky!)
Hee! The police missed a lot of explosives all over the place apparently...
Seriously - if you live in Gotham, check the car before you get in. Check the basement when you get home, get to work, go to the hospital, eat in a restaurant...
re: why not quit?
Because he can't. Most of Bruce Wayne's story is more implied than explicity shown in this movie, but it's all there. If the Joker is a dog chasing cars with no purpose, Bruce is portrayed as a bloodhound who'll follow right over a cliff before he'll give it up...
But he *does* decide to give it up (according to
Emh above) - though it's not clear to me when Dent, Bruce and Gordon devised their plot. For things to make sense, it must have been before the attempt on the Mayor (when Gordon goes into hiding) but Bruce seems sincere when he decides to reveal himself... ?
I think that theme got short changed. It can't happen now, but I wanted to see Dent live, and now Gotham has two lunatic criminals, both inspired by Batman, and the war escalates, and the city suffers, and the only way Bruce knows to fight back is by throwing gasoline on the fire.
There are implications that Bruce takes on Harvey's crimes as much as self-punishment as anything else.
Now there's an interesting idea that can be tied back to his origin. Is Bruce punishing himself for surviving the attack that killed his parents? and if so, then assuming more punishment is right in character. I like that... but I'm not sure it's entirely intended by the filmmakers.
This is to the poster above who said he didn't see the detective work ...Lau's role as money launderer ...the entire plan to knock out Lau Security Investments ...how to get the fingerprint off the shattered bullet
I thought the movie did this very well with very little time - I don't need to watch him dust for fingerprints. The bullet extraction/recreation was exactly what was called for.
One last detail sticks out - the prisoner's decision on the ferry. I'm sure it's been kicked around upthread, but at the time, during the movie, it didn't ring exactly true. (The civilian one worked, though it was fairly unnecessary after we'd seen it once) The prisoner's decision was another moment where the film seemed more dictated by the writer than by their own possible motivations. Not that the actions were inexplicable, but ... more for the sake of advancing the theme than anything else. Did other people think the same?
