A crappy Fantastic Four movie wouldn't qualify as harm, unless there was good evidence that they were deliberately trying to torch the franchise; a Fantastic Four movie where Reed is a pedophile, Sue a prostitute, Johnny goes around burning people to death for kicks, and the Thing is a serial killer would.
I remember that if Fox hadn't made FF or Silver Surfer by a certain time they would have LOST the franchise and owed Marvel money (I forgot how much). Just didn't know about the damage to the characters
