We can go back and examine all that now, but the willful suspension of disbelief only goes so far. I don't remember much of Batman Begins so I can't comment on that, but who's not to say that I wouldn't pull punches on that? The Dark Night is the better movie of the two, and for good reason. One being the portrayal of the main villain. The Joker isn't some crazy mystery. We know who he is and what he's up to. Of course, we don't know all the details of his plan, but that's to be expected. Besides, the whole bomb scattering thing isn't a question of just plain weird characterizations or anything. Mr. Freeze is a one trick pony, and I just can't imagine how a guy who freezes people can be taken seriously in the kind of movie that is looking for realism. Bombs, knives, those sorts of things, they're all real, and that's the attraction. Freeze rays? I don't think so. AFAIK, he's not even that important of a villain in the mainstay of the series.
