>>98301988All FF runs are basically Talmudic commentaries on the Lee/Kirby run.
It's like every X-Men run since 1991 has been about how the writer feels about Chris Claremont's run.
Not every comic is like that (Simonson's Thor isn't all that much like Kirby's and it's probably become the definitive run), but FF is the comic whose original run casts the longest shadow.
