I thought that too, but if you notice, the other side of the road is also blocked off. I've seen the film four times now, and trust me, I noticed the other side of the street being blocked off, so the convoy had no other choice but to take the lower route. The cops do notify the SWAT van of the garbage truck, but Joker's semi pummeled it into the river and then proceeded to quickly dispatch the other remaining cop cars. It's not like they had much time to coordinate anything, since the moment they arrive in Lower Wacker, the garbage truck arrives, and then quickly after that so does The Joker. I think you just answered your own question. I'll agree with this. I also found the lack of music to assist in making the sequence feel less engaging and more plodding along, as you say. It's not as efficient or engaging a sequence as the car chase in Batman Begins, for example. Perhaps. I liked the quieter scenes in The Dark Knight just fine, though, whether or not it was Alfred consoling or offering advice to Bruce, or Rachel talking to Alfred about the nature of heroism or when she's alone with both Bruce and Dent...I thought they were plenty of quieter moments that easily outshined the moments in Batman Begins. I think my favorite "quiet scene" is after Rachel is killed and Bruce is in his penthouse, and Alfred consoles him. It's a clear homage to the scene where Alfred consoles a much younger Bruce after the death of his parents, and the music even mirrors that scene, almost cue to cue. I think the character in itself is just weak and not as interesting or well-developed as the others, but that's my personal opinion. I don't think Gyllenhaal did any better, but I think she did pull off the assertive, spunky, capable woman more than Holmes did. I also fret the way Holmes would have handled the warehouse sequence. Some of the music is lost in the film, but listen to the soundtrack, and especially the expanded soundtrack. Batman is given a full-fledged theme and a "sound" (a la The Joker) and some of the action beats are much more realized and enjoyable. While I will agree that the only interesting themes are the ones carried from Batman Begins, I think Harvey Dent's tragic theme is pretty good.
