Not to turn this into an argument, and I strongly believe everyone is entitled to an opinion... I just wanted to offer a counter argument on a few things you said here Shallbecome...
This is exactly how I feel about Nolan's Dark Knight. There are LARGE chunks of that film that add absolutely nothing to the plot and feel like padding. The Hong Kong plane sequence, the bullet analysis scene, the faking of Gordon's death and quick resurrection, the sonar fight (when simply telling Gordon that they are all innocents would have worked)... etc, etc, etc. For me, adding superfluous scene after superfluous scene in an attempt to shoehorn a bunch of ideas into a story adds up to a film that really doesn't make sense when you really look at it. I never get that vibe from Burton's Batman films. Almost every scene is necessary to the overall film, like a moment isn't wasted. And at the end? The film makes perfect sense to me- It is a live action comic book version of Batman. Take a sequence or two out and it probably wouldn't though... I can't say the same for Nolan's films.
This one is really easy. First off, Batman is quite far away when he hears the screams of the mother at the beginning of the movie... He couldn't exactly stop it since it already happened. As for why he beats them and leaves- It is all about the "Legend of the Batman". He isn't just beating a couple of perps for a bad deed. He is using the encounter to spread the fear amongst the criminal element. This is why he says "I want you to tell all your friends about me". Batman is after all just one guy, and he is pretty new on the job at the beginning of '89 Batman. Spreading the fear by word of mouth in the criminal element helps his legend grow, and the fear it instills will stop some crimes before they even happen (as evidenced by the worry about him from the very 2 crooks we are talking about). The fear he spreads amongst Gotham's criminals is his ally.
I have argued this one before as well... A couple of points:
-Since we are looking at the first few weeks of him being Batman, it is a good bet that the Batwing is a relatively new piece of equipment, possibly untested. This may add to its unprotected state.
-Hitting a stationary target on the ground the size of a person isn't an easy task for an AERIAL combat vehicle. The Batwing was chosen as a means to take out the balloons and save lives as fast as possible, not for an actual assault against the grounded Joker. I am sure once the balloon threat was over, it was simply a matter of trying for a lucky shot as a secondary objective.
-Joker used an explosive charge in the gun (this is explained in the comic adaptation).
This one just isn't true... Joker killed many, MANY people that we don't get an accurate count of onscreen (the tainted product deaths, possibly all the folks in the museum, the parade attendees, etc). Does Batman kill in the films? Yes- With the basis for that being that Burton & Co. were taking him back to the original appearances where he did kill in an effort to distance themselves as much as possible from the 60's stigma...
All my opinion of course.
