Over-hyped and over-rated; movie makes no sense at all

Rating: 1/10 (10 March 2018)

After 3 straight comedies (GotG2, SMH, and Ragna-joke), MCU tried to copy DCEU by making a serious movie. But if Black Panther is supposed to be a serious movie, then Black Panther is a HUGE FAIL because Black Panther doesn't make any sense at all.
1. T'Chaka flew his aircraft to a neighborhood in Oakland at the beginning and T'Challa did the same thing at the end. The US government wouldn't just allow a foreign aircraft to fly over US airspace (especially after 9/11) and hover over or land in a US city. So Wakanda violated US airspace.
2. T'Chaka tried to arrest his brother and take him back to Wakanda for execution. Even if his bother did break the law, he's on American soil and T'Chaka has no jurisdiction to arrest him on American soil. T'Chaka would have to request the US government arrest his brother and extradite him to Wakanda. But the reason T'Chaka didn't do that and instead tried to covertly take his brother back to Wakanda for execution is because T'Chaka was afraid his brother would request political asylum from the US government.
3. T'Chaka kills his brother and just leaves without taking his brother's body back and giving him a proper burial. Even if T'Chaka has diplomatic immunity, he just killed someone on American soil so by law he still needs to report that to the US authorities. Instead, T'Chaka just leaves his brother's dead body there for his young son to find. Imagine a young child finding his father's dead body like that!
4. Klaue was arrested on Korean soil. Why the hell would the Korean authorities allow an American CIA agent (basically an American spy) and a Wakanda national to question a suspect arrested on Korean soil?
5. Why would the Korean government allow T'Challa to take a wounded American spy to Wakanda? 1 MCU fan said that South Korea is on friendly terms with the US, but that's irrelevant. He's not only an American citizen but an American CIA agent. The US government might not want a wounded CIA agent transported to a country that Americans aren't even allowed to visit and potentially drugged or tortured to reveal state secrets.
6. Since T'Challa accepted Killonger's challenge and Killmonger defeated T'Challa in combat, Killmonger was the rightful King of Wakanda. So the American CIA agent was basically participating in an illegal coup against the rightful King of Wakanda when he helped T'Challa take back the throne. Shouldn't the rogue CIA agent call Langley first to check if he has permission from POTUS to participate in an illegal coup against the rightful King of a foreign nation and potentially involve the US in a war that POTUS might not want? After all, POTUS might prefer having a former American soldier on the throne of Wakanda.
7. If Wakanda had all that medical technology/process to heal people and save lives, then why did T'Challa just let Killmonger die when T'Challa could've saved him? Because Killmonger didn't want to be in prison? But why would Killmonger be in prison? Killmonger didn't break any of Wakanda's laws. Killmonger was the uncle's real biological son so Killmonger wasn't an imposter. Killmonger challenged T'Challa for the throne, which Killmonger had a legal right to do by Wakandan law, and T'Challa accepted. Killmonger defeated T'Challa in combat so Killmonger was the rightful King of Wakanda according to Wakandan law. And as the rightful King of Wakanda, Killmonger had the legal right by Wakandan law to order his army and his ships to go outside Wakanda and wage war. So what Wakandan law did Killmonger break? Why would Killmonger be put in prison when he didn't break any Wakandan laws? Is it just normal policy that the King of Wakanda can just throw anyone in a Wakandan jail just because they challenged the King?
8. If Wakanda is supposedly the most technologically advanced nation in the world, then why are they still resorting to a medieval and barbaric and savage ritual of choosing a leader by violence and bloodshed and mortal combat? Is no one in Wakanda smart enough to come up with a peaceful way in the 21st century to choose a leader that doesn't involve violence and bloodshed and mortal combat, especially when most of the rest of the world has already done so?
9. If Wakanda wanted their King to prove himself worthy to lead the nation, then why would decide their King by mortal combat? Wouldn't a supposedly technologically advanced nation want to choose a King who is the smartest rather than just choose a King who has the most brute strength?
Black Panther is just another over-hyped and over-rated MCU movie that is full of awful writing.
