I read the FF comics and I admit it used to be following a pattern. Ben would either be working out or walking around NY, Reed would be in his lab with Sue nagging him to spend time with Franklin or the family. Johnny is either trying to get a date or working on a car. Either that or Ben and Johnny would be fighting.
I wonder what they have planned now that Franklin has his powers back and Val is a mini genius. I enjoyed the run of comics with the Black Panther and Storm in the group, even if The Black Panther comic wasn't in sync with the FF comic and you found out the end of a story arc half way through the story arc.
I agree that the roster will always be the original 4 maybe 6 if you count the children. I thought the team up of Spiderman, Hulk, Ghost Rider and Wolverine was funny when you think about. Spiderman was the replacement Reed due to his smarts. Hulk was the muscle, instead of Ben. Ghost rider was the replacement Human Torch. So Wolverine replaced Sue. I wonder what Logan would say if you told him he was the replacement for the woman in the group. I think it would start with a few %$@" signs then SNIKT followed by AAAAIIIIEEEEE!!!!!!!
