Bruh, Letitia was the side kick, not the hero. She was good, and a fan favorite, but it takes more than that to carry a franchise.
Well..besides the charisma she showed. Wasn't like she sat on the sidelines and watched everybody else stop Killmonger.
She played a pivotal role as well, from fight to her tech.
So again.......... .......she might be able to pull off the role.
Y'all outright dismissing her, is crazy. Anybody else y'all can possibly think of to play BP would be a question mark just like Letica.
