I never read novelization of movie et novelization of comic because I don't think this is a good «creativity process» and don,t really believe in the result. I decided to make an exception of this one, The Killing Joke (comic) being so damn good I have to try this one. I should have stick to my original mind. This wasn't good. The writing was not bad, but far from bringing something more to the comic, which I though should have been the strongest element, the story was already good in the comic, so you have to bring something new, which left you more or less two choices, the writing or the psychology of the characters. That second point wasn't there either. So both elements that could have elevate this story were not there. I also think that the introduction to the Batman world were rush and at the same time unnecessary. It really depends were you want to go from there. If you have in mind to produce more Batman novel, then just make a novel that put the universe in place and don't start with a iconic one like this. If not and you address your book to people you already know Batman and who are just there for that book/experience, then don't bother making look like an intro in the first quarter of it. That being said, I isn't entirely bad and it wouldn't be fair to make it look like it. I think that younger reader, you haven't read the Killing Joke or even Batman comic, and are not necessarily comic fan, may enjoy it. I don,t think this book is for comic reader of the Batman universe, but is more targeted to conquer a new public, to the DC/Batman universe. Maybe I'm wrong, it's just my impression. Bottom line, not entirely bad, but far from good either!
