Martin's traits that you are saying are bad or negative things, (at least that is what I think you are saying) are also the exact same traits that allowed him to take a book about a comic strip character and turn it into a Hit Broadway Musical. He obviously has something different/unique about him because he has accomplished something that very few people can say they have. If all it took was being a nice normal average person to create a Hit Broadway Musical then I think it's safe to say that there would certainly be a whole lot more of them then there are.
As far as saying that: Mr. Martin Charnin has...Annie. That's it.
