I don't really think the sonar was all that ridiculous. Sonar itself has been around for decades, and I don't think it would be much of a stretch to make a pocket-sized version and then network a whole bunch of them together. Perhaps they overdid the presentation of it, but it really didn't take anything away from the movie for me.

I was curious about that, too... and I don't really have an answer because either would have been equally plausible.

Spoiler: I think that they kept things open-ended like that on purpose because they haven't yet decided which direction to take the next movie.

After all, they hid the fact that Harvey became disfigured/killed those people from the public to preserve the hero image of him. So to me, the fact that they publicly declared him deceased doesn't mean he really is dead.

As a side note, what bugged me most about the movie was Two-Face's disfigured side. Most of it was badly charred, which doesn't make much sense since he was only on fire for a couple seconds. If you get past that and accept that he was burned that badly, what about the critical parts that remained fully intact (like his eyeball, jaw muscles, teeth)?

My guess is that they initially planned for his face to be "melted" by the liquid when he tipped over his chair and knocked over the barrel, but couldn't do that and still get a PG-13 rating... so they changed it mid-production.
