Penultimate "Fantastic Four": Marv Wolfman praises Mark Waid's stint on "Fantastic Four," crediting him with reinvigorating the franchise:

"Mark went back to the inspiration of how we remember those early FF stories and re-created that without ever doing what had been done before. Also, he did it without immediately bringing back some old villain. More importantly, he has gone further than anyone, Stan included, to make us care about the core FF characters as well as the stories they’re in. For the first time, perhaps ever, I have a clue to who the characters are."

(Note how Wolfman mentions Walt Simonson's run on the series, but avoids any reference to John Byrne.)
