I dont think either, necessarily. I believe creators have had input on the X-Men franchise but I can't remember anything said about assistance on any of the FF films, and though I'm probably mistaken, same with Spidey.
It's idiotic to believe that Fox wouldn't consult actual comic book creators for this film.
Comic book writer Mark Millar is listed as a creative consultant on the FF movie.
You know, Mark Millar who wrote the first story arcs of Ultimate X-Men, The Ultimates, and (with Bendis) Ultimate FF. He then wrote the primary FF title for ~20 issues or so in 2008-09.
He also wrote Marvel's Civll War and Old Man Logan storylines, and created/wrote Wanted, Kick- and Kingsman: The Secret Service.
Filmwise, he's served as a creative consultant on the first Iron Man, as well as the film adaptations of his properties (Wanted, Kick-). He's also serving as creative consultant on X-Men: Apocalypse and (duh) Wolverine 3 (since he wrote Old Man Logan).
You can prematurely hate on the FF film because they're adapting Ultimate FF, but at least they brought in the dude who literally established half the Ultimate line for this movie. And a guy who has had no fewer than six of his comic book creations turned into major studio films (including the forthcoming Cap sequel).
I meant no disrespect to you or Mark Millar, and I stand corrected.
I also want to point out that I loved the little bit of UFF I have read, and never once have prejudged this upcoming movie based on it. All my nitpickings have been things I've seen in the trailers and stem out my strong desire for the FF to join the MCU.
