Same here. This whole "Waid used to be GREAT!" thing is rose-colored glasses.
He did the first decent Captain America run a lot of people of a certain age ever read, so they think it was a "great" run.
Kingdom Come is only a borderline classic due to Ross's art and concept. The writing there wasn't that great. It was just good-ish.
His '90s Flash run got a lot of love, but there again I think it's just a case of "This is the first not-horrible Flash comic I ever read".
His Daredevil run again wasn't that great. The first six or so issues WERE really good, but the quality slipped rapidly. Do you really care that much about Sons of the Serpent or The Hole or anything else in that random run? It wasn't bad but I never got the love for it.
He's never done anything great. He was never an elite writer. I wouldn't even put him on Busiek's level let alone Morrison's.
But yeah he's left of center and anyone left of center has been pulled into the blackhole of crazytown in the last couple years.
Screw him. If I ever saw him in person I'd punch him in the face for no reason and laugh..
