Hate to break it to y'all but T Challa wasn't gonna replace Tony. They wouldn't even let him be cool in his own movieDon't include reynolds, marvel product but fox produced movies, and again we are watching this phase with hype color glasses. Phase 1 and 2 weren't flawless they were some mids and some duds. I think again not to put this all on a Black man. But I belIeve Black panther was going to step up and play that Tony stark Role and his death (RIP) might have fukked that up. Its a simple fix though just bring MBJ Back from a different timeline after this black panther film. Stuff is watered down a bit (BP death/pandemic rewrites/reshoots and filling in the D+ stuff). And add a toxic fanbase that refuses to accept that the first 3 phases weren't perfect neither.
Again lets not forget the duds/mids from phase 1 and 2 and even 3 had some Mid in it. We just look at it as gospel cause of infinity war and end game. The latter which was dope in its own right but they were some missed opportunities there too. Again is good that most of the A Tier marvel IP's after 2023/24 will fall back to marvel solely like The Hulk, Xmen Doom stuff thats why I believe they are not announcing many phase 6 stuff and probably sprinkle in a lot of cameos for phase 5.
Civil War was the coolest BP ever looked and with the Russo's gone....
They would never give T'Challa a scene like Tony's in Iron Man 2 where he tells Congress he ain't giving up SHYT and y'all owe him a thank you
One of the GOAT MCU/Tony scenes in my opinion
They were NEVER gonna let T'Challa boss up and flex like this so that "T'Challa replacing Tony" shyt is a pipe dream
