I’ve noticed that the more powerful a superhero comes the more limited his story space (the types of stories told with the hero) becomes.
A great writer can make any character interesting. But when you are talking about corporate comics(marvel/DC) you are talking about writers of various levels writing over decades. I find that the more powerful a character is the more the level of writing has to be incredibly high to keep them interesting. That’s why I feel Batman has dominated the way he does. Even an average or inexperienced writer can turn out an interesting Batman story.
I think it stems from the fact that weaknesses (what a character cant do) is just as pivotal to a story then powers (what a character can do). With a lot of Uber powerful superheroes, their is very little they cant do so the list of potential obstacles and challenges is a lot shorter for them.
This explains why Batman, Spider-Man, Daredevil, and even Green Arrow(to a lesser degree), seem to be able to turn out somewhat memorable stories at a rather consistent pace, while characters like Superman, Silver surfer, Green Lantern, and Thor often require spectacular runs by the top tier creators in the industry in order to get the same level of buzz.
