I think I give it this five star rating just because I'm really excited for the animated movie to come out. This comic is pretty messed up, but I liked learning about The Joker, and his backstory, but also Batman in this comic was very interesting as well. The beginning and ending parallels were beautiful, and the art work was amazing. I can see why this became cannon for the DC comic universe, and the Batman universe too. 
 The Joker is one twisted mofo. 
 Everyone has bad days...but not to that extent I suppose.
