Based on the oh so tepid reaction to the Man of Steel in the other thread, I thought I would offer up some Superman comics that I've read and enjoyed.
Now mind you, most of these are Elseworld tales so you can read them on their own without knowing too much of the history.
But sure everyone knows the gist of his story.
If you read one story on this list, read
Superman: Secret Identity
These are just 4 mini-series that deal with the character of Superman/Clark Kent. There are other interesting stories but those bring in characters like Batman and Wonder Woman.
