Sorry! I was thinking about the movie more!
And, like, look, I get what was happening here: Chadwick Boseman dying was a tragedy, and Black Panther 2 conflates the actor with the character, and takes a very well deserved look at grief and how Boseman touched so many lives with his roles and should be celebrated in the same way as a deceased monarch. That was cool from the "meanwhile, in reality" perspective.
BUT! T'Challa had to be the worst king in Wakanda's history, right?
Here's the timeline as I understand it.
T'Challa takes the throne
About seven seconds later, his idiot brother takes over
After a long weekend, T'Challa is back on top
His first royal act is dissolving Wakanda's centuries old isolationism, and announcing to the world that Wakanda has a monopoly on the most valuable resource on Earth.
No, Wakanda is not sharing.
But we will build one (1) Youth Center
A couple months later, a big ol' war with an alien army
That had to have insane casualties, right? Like, a whole lot of locals facing a literal death cult with technology never before seen on Earth
And they didn't even come close to winning.
And, at the finale, T'Challa disappeared for five years, presumed dead.
I think his bodyguard was in charge for that time?
T'Challa's back! The king returns!
Then he died again.
So... uh... I get that his family is going to be upset, but I feel like it would have been cool if the public of Wakanda was like "hey, maybe this royalty isn't working out."
