The first issues of the FF not written by Stan Lee were…Pretty lame. But than, I think Diablo is kinda dumb anyway.
The most novel thing about this two-parter was that it featured the first ever Thing solo adventure as a back up feature. Very unmemorable. Next issue will be written by Avengers writer Roy Thomas and would feature Avengers member Black Panther. It would be much, much better.
