There’s still Ben to show the average person versus reed. I don’t think it’s boring. It would definitely be more boring if he was this amazing intellect and her only job was pointing at stuff and saying “what’s that?”
Except in a modern context... Ben wouldn't be "average". A modern American Air Force pilot isn't some cliche' from a 1940's/1950's movie. We are talking about people that have to have as part of their job, a more than layman's understanding of aeronautics, engineering, physics and even computer sciences. That's not to say a modern Ben should be able to follow all of Reed's thinking on cutting edge astrophysics or Quantum theories etc. but he's not gonna be the "average" person either.
Look I just think that having everyone on the FF with an academic background of some kind has been tried before already and it's not yielded much, plus it's not necessary. They all bring important character aspects without having them all simply be "less smart geniuses than Reed" type characters in my view. I don't think it's some kind of slap in the face of Sue, or women in general if she's not a scientist. That in no way means she's "dumb". She's just... not a scientist. If anything writing her as still essential and useful despite her not being a career academic or doctor of some sort can be inspiring in it's own way. Let's look at the MCU to date... Who's actually got a background of not being in the sciences or the military/covert ops that's from the Earth based side of the Marvel U.?
Iron Man- Scientific genius
Cap- Military war hero
Banner- Scientific genius
Thor- Asgardian Space God
Black Widow- Covert Ops
Hawkey- Covert Ops/Military
War Machine- Military
Falcon- Military
Black Panther- Scientific Genius
Dr. Strange- World recognized Neurosurgeon
Peter Parker- Enrolled at school for scientifically gifted students
Nick Fury- Military/Covert Ops
Winter Soldier- Military/Covert Ops
Scott Lang- Engineer
Hope Pym- Scientific genius
Who's the odd man out on that list? The SPACE GOD.
Fine... The GOTG and Wanda are not all scientists or military and while Vision is neither as well... He's a freaking android. So far Wanda is the sole truly "average" human being. If there is a perspective lacking in the MCU it's that of someone who is not either attached to the military or the world of science in some fashion. Even Capt. Marvel is going to be an elite educated graduate of the Air Force Academy. Maybe Sue and Johnny not being written as science majors of some kind is actually refreshing and could yield more in terms of interactions than if they are just, again... Slightly less genius than their genius team leader type characters.
I will also add this... You don't have to worry about writing your characters as making decisions that aren't "smart" if you don't give them pedigrees where they should be informed on some subject but then act diametrically opposite of what you are selling them as. I've talked about how Johnny in the Story films in no way sounds or acts as someone that was an astronaut would. An even better example is the first Jurassic Park sequel. Julianne Moore is supposedly and expert on hunting animals. We're told again and again how brilliant a naturalist she is... Yet when it's pointed out that she's walking into raptor territory with the blood of a wounded dinosaur on her clothing she shrugs it off... That's just stupid writing and does her character no favors. Again... Sue isn't automatically "dumb" just because as a character she doesn't have a PhD. She and Johnny bring other things to the table in the team dynamic that Fantasy super genius Reed and gruff yet bold test pilot Ben don't. If the script handles Sue and Johnny well in terms of who they are as characters and how they interact with the other two then there's little need to rationalize their inclusion in the story by giving them roles that traditionally in the comics have never been necessary and in no way puncture the suspension of disbelief.
