The Joker's Last Laugh was the last Batman graphic novel that I bought in Toronto back in November. And of all of the Batman graphic novels I bought, this one is my least favourite.
It started out with a pretty good premise. The Joker has been diagnosed with terminal cancer, so he goes crazy and plans his last laugh. I think my problem with the whole thing was that it was a major cross over. The Joker's Last Laugh didn't just feature other villians from Batman; no it featured villians from all over the place in the DC multiverse. And I really don't know who the vast majority of them are.
Another thing that I didn't like was that Batman wasn't really a major part of this story. I bought it thinking it would be a fun battle between the Joker and Batman. But Batman only showed up every here and there. The Joker's Last Laugh was more about Barbara Gordon and Dick Grayson. Well, and the Joker as well of course. I think Batman only showed up like two or three times in the story. And he never punched the Joker out the way they show on the back of the book.
So as far as Batman stories go, this one really wasn't one. If you like cross over stories, you'd probably like this one. But otherwise, you're probably better off passing this story up.
