my point was that there was no closure to the joker story, it didn't seem like he was ready to retire to the costa del sol at the end of the movie, so how are they going to explain his absence in the sequel. they cant just not mention it, and any atempt to explain his absence is going to seem pathetic. also any other vilain is going to be be so lame when measured against the joker now. i think it was the fact that he was doing it all for shits and gigles basicaly, that realy set him apart.
