I am no movie critic and this is not a review. Just the opinion of some boy somewhere in Africa.

So I'll go easy on you because of the quoted text above...
I like your point of view but then how about we see the good in the bad. If they had not chosen/made a reference at all to Nigeria, I am pretty sure you would have mentioned that as part of the points listed on your reasons for critiquing the movie. Here is something you don't get, the movie is trying to incorporate several African cultures and create an Africa we so dream of. TBH, this is a major step up from the usual stick and stones mentality they have/had.

Furthermore, if our house of macro which is one the leading special visual effect company in Nigeria were to step up, we wouldn't have to have someone else define Africa for us.

T'Challa's attitude can be perceived as weak, at the same time, it can also be a major strength. Weak in the sense that he is slow to make us his mind and strong that he exhibits self control unlike how some real African kings actually behave.
Life offers choices, we don't say because WE SOLD OURSELVES into slavery (because the black man actually sold his kin more than even those that were forcefully taken away) and we were maltreated, that makes the white man the bad guy. Do you know black people are even more racist than whites, the only difference is we feel it's okay when we do it and not when others do it.

Erik's plan would have caused total breakdown of law and order. Give all the black people guns and do what? Kill everyone who stands in your way?? He ain't the only one pained, T'Challa watched a bomb blast kill his own father by Buckey Barnes and he still helped Bucky eventually. That is the true strength of a leader (African or not) and I am proud he is African .

Let us assume everyone pained now has a weapon, the "enemy" somehow gets their hand on the weapon and it's fire for fire, total breakdown, guess what? we become the savages we are calling others. Based on that Erik, though a firm king, was not wise.

Lastly, instead of yabbing Hollywood for not really involving Africa in the production process or post production credits, how about we tell ourselves the truth...we wake up and friggin develop our own movie industry. When Nollywood reaches that level of visual effect/CGI wonder, then we can talk about (or critique)a multi million dollar budgetmovie running into billions of Naira, but until then, we can only say awesome movie.

P.S. mercy is not weakness, it is the strength that is rare to find.
P.P.S. Maybe Erik should have drunk the potion that also weakened T'Challa too as Erik is well trained. Only then will we see if it was a fair fight.
Thank you
