First of all, I really did not pay attention to the first half of the movie cause I was busy talking to my friends.
My first question is asking the fate of joker. As you recalled your memory, you will remember he was hung on the top of the building by batman. Then the scene of the movie switched and never mentioned the fate of joker until the end. I think the director might leave the audience to decide the joker's fate.
The triggers of the bomb should exist in more than one boat. Thus, even if the people on one boat threw them away and batman stopped joker for another trigger. There should be other triggers exist on other boats. That means some crazy people would still explode the boats.
