It's not a dumb take. Civil War T'Challa exuded the regality comics fans always knew him for
Black Panther competently displays the hero's journey, but there's a confidence from T'Challa missing that Civil War featured prominently. Most of this is on Coogler because he spends significant parts of his movies giving subtle apologies for elements of blackness. This is present in nearly all of his written projects
Black Panther T'Challa doesn't have a scene as raw as this
A 10 second exchange that tells you everything you need to know about T'Challa and the nation he now leads. The theater erupted after that shyt
All of your points are true but it's funny that you use T'Challa almost killing Klaw as one when a significant piece of the plot hinges on the fact that T'Challa didn't kill Klaw.
Breh that scene has more to do with somebody ready to throw down on Black Widow. Thats why people erupted. Nothing he does here is different than Black Panther.
More of it comes when Okoye was ready to dead Ross for T'Challa. He simply defuses it and puts a bug on him in Black Panther.
If anything the difference is he's still in demon time/blood thirsty mode in Civil War. T'Challa was actually very sloppy at times in Civil War, but he looks badass and its cool to see him charging the Avengers so its ok.
Black Panther focuses once grief sets in after you're done being angry. Now you can disagree with the choice to go that route, but everything is there about the character.
