i'll be the first to say heath did a fantastic job with what they gave him.his was a joker character not often seen by the batfan.but i think i can speak for most and say his joker was really fantastic.now that said,i'll just say what we,(the fans who read detective,and batman),know 100% that this was not our joker.our joker is emaculately dressed,very spiffy,and in a psychotic kind of way,deleriously happy.now heath's joker was perfect for the way it fit in the movie.he actually reminded me alot of a baddly whipped dog.but this was not our joker.so to think of not using this character again is as insane as,well...you know who.i'm about 98%sure they planned on using heath as the joker in the next movie.it's really very simple.joker goes to arkham.joker meets harley,(or whomever).becomes a new man,and cleans himself up to become,tadaaa,our boy.then he and harvey try to kill each other and everyone else in gotham.seems simple doesn't it?i think this whole story was meant to be played out in 2 movies and heath passing on put a kink in it.but they could use this to thier advantage as in "new joker,new guy".
