I personally would’ve been fine with 3 solo movies before passing the torch on to someone else. That’s plenty of time for audiences to experience the character plus a few team up movies. And it would’ve allowed T’Challa to have a complete character arc like Steve and Tony. Sadly his story is getting cut short unless Marvel pulls some multiverse shenanigans or (gulp) the T’Challa Jr rumors are true and they pull some Kang/time travel shenanigans to age the kid up to spare us a decade long wait to have someone named T’Challa in these damn movies going forward. Lmao.
