What Makes A Good Superman Writer?

I found this discussion of Joe Kelly on The Fortress Of Soliloquy

I like Joe Kelly a lot. In fact, I think he’s one of the most underrated writers in mainstream comic books. His run on JLA had a few missteps toward the end, but it was easily as good as Waid’s tenure. To Superboy, he brought a great sense of humor (and consequently had one of the few readable “Last Laugh” tie-ins) as well as some striking emotional content. Even his run on Supergirl had the seeds of brilliance, which is particularly amazing considering what he was given to work with. His Superman/Batman Annual[s] have been top-notch, and I doubt that I even need to mention Deadpool.

And it made me realize how strongly each superman fan feels for his favorite writer.

It is a little strange that there are so many writers for the same characters over the years and each of them was able to bring something uniqu without breaking the superman story.

I have read superman by at least four different writers over the years and if we think about it like a chain than each writer brings his own unique perspective but still writes superman, meaning he can’t really break the boundaries of the story and has to be loyal to what we already know about superman and what we would know in the future.

Thinking about it it is a more complex task than it seems, sort of entering a tv show after few season writing a season or two and letting others continue.
