Well, Superman was pretty irrelevant in my book by that time anyway. The reboot of the character that I look back at fondly involved a sand creature back in '72 or so. Um...I guess you had to be there...
Oh, good God, I remember that issue! He lost two-thirds of his power, which gave them an excuse to nix the truly moronic super-powers, like blowing out suns or flying faster than light and so on. The "big" reboot in the 80's, with John Byrne was a good idea in theory...the only trouble was that Byrne was an average writer at best and a truly terrible artist IMHO. "Kirby without balls" is how a friend of mine liked to put it, but mainly his art looks ugly and amateurish. To ME anyway.
