In top 100, sure. But he has 3 in the top 5. And the first place is Watchmen (which I also consider overrated). I just think it is too much compared to other writers. I would not put that many deconstructions and "dark" storylines that high.
But that is a general peeve of mine that people tend to consider the darker, depressive stories to be more "mature", or meaningful than the more lighthearted.
