I know someone would use that argument.
Ive read many comics starting in the 60s, and I never saw Cyclops as a dick, I always connected to him, and his look never gave me "he's a dick" either. Fox universe problem (one of them) is that the audience never connected with their Cyclops, so Marvel would have to be really careful with this casting, signing an actor who general audience can empathize with him, so thats why his look is very important, imho.
There are actors and actors, you can be tall, commanding and sexy if you want, but still feel human, empathetic and with some charm, even if the role is written to be a serious guy.
That actor in particular didnt give me that vibe, and as I said weeks ago, I saw Darkest minds and something turned me off.
Tye Sheridan for example hasnt the perfect look/image for Cyclops, but I always connected with him in his movies, there is something raw, authentic and real in his acting, and never seemes like a dick in Apocalypse, in terms of look Im saying. So this to me is very important to make Cyclops an A-list and a fan favourite. Marvel can easily nail all these points if they sign the right guy (similar to Chris Evans, that kind of give all this vibe)
