I've never been one to buy into the argument that Superman is not a compelling character because he's too powerful. There are countless characters in the comics that can stand toe to toe with Superman.
However I feel like Superman's super-hearing should be toned down. Being able to hear everything on the planet would make him privy to the conversations and schemes of any villain. I give Bendis credit for addressing this issue by having the Invisible Mafia operate out of a hideout made of lead, but there's only so many times you can pull that card as a writer.
Personally I would just retcon Kryptonians only having their super-hearing extend to a couple miles radius.
