Jason Todd was a great Robin till he started acting like a jerk. (He came back as Red Hood then he was a bigger jerk.) He is a young boy who wants to see justice in the world and Batman is reluctant at first to train him. But like always, Batman starts teaching Todd about ways of the world and Todd is a fast learner. He is a mouthy young guy who is witty and is probably more closer to the mold of Batman than any other Robin. 
 The violence involved in killing Todd was a bit too much. Maybe it was the time when comic books were changing and catering to much older audiences but in the end - Todd is still a very young man. It was disturbing to read the parts that lead to his eventual demise. 
 Its a good story (Joker is Iraq's ambassador!), the line Batman never crosses etc. However with too many coincidences and some unbelievable plot line, the comic becomes good and not great. 
 Its still an arc that no fan should miss. It has good writing, bit dark ink work but overall good art.
