Over at The Portalist, Stephen Lovely has a response to the common criticism that Superman's powers make him a dull character. Lovely concludes:
Superman is a serious character with real conflicts. His superpowers
aren’t an obstacle to good storytelling any more than most characters’
lack of superpowers are. Superman’s best stories exist in part because
writers don’t have an easy crutch to lean on, and that’s an asset, not a
weakness. It’s something that, when managed correctly, makes Superman
the most rewarding superhero character of all.
I tend to agree.
