You came to this conclusion how? T'Challa wasn't ALWAYS out for the kill prior to learning the truth about Zemo and secondly, he was the only one that went toe to toe with a brainwashed Bucky and bested him physically without his suit. Not only was that a clear demonstration of his superhuman abilities but then there was his speed in which he outrank cars, outpaced Bucky aftet taking a direct punch from Bucky's arm and being knocked down only to immediately get up and rush to get to higher ground and jump across down to meet Bucky again. Then there was that casual jump over the railing, landing on his feetwhich was from about 50 ft height and of course his double jump kick against cap and catching 2 exploding arrows shot from Hawkeye. To say these are examples of not being all that superhuman is just flat out false; especially the aforementioned scenes with T'Challa out of his suit. As for IW and EG did you not see BP's superspeed when he and cap ran ahead to lead the charge in IW then in EG him running the gauntlet scene and immediately getting back up after taking a forceful hit from Thanos' sword? The same sword that shattered Camp's shield. Besides, the appearances BP has made outside of his own solo film have been limited, especially the last 2 Avengers films so we're obviously not going to get to see much of anything from him BUT his own solo film...that's his stage and space to showcase T'Challa's dexterities which are lacking.
I simply don't agree with this in the slightest. Which scene are you referring to?
You can forget Priest. He hated the BP movie and he's not interested in writing or working on projects with black protagonists anymore. Hudson at least has a relationship with Bozeman and I love his run on the comics. 'WITBP' is one of the best BP stories that shows the strength of character of who T'Challa is, who the Wakandans are and showcases a BP that is unashamedly black, African, powerful, charismatic, confident, superiorly skilled fighter that kicks ass and isn't about that bs. Hudlin's BP is the most accessibly cinematic version of the character.
The only fight that could argued that T'Challa was fighting seriously was against Cap but even then that fight was extremely disappointing. Cap dodges/block 99% of what BP threw at him and BP had WM backing him.
The forest fight in BP is when he did a far better job than them. T'Challa used strategy here and was well thought out. He disables the trucks and gets the traffickers to exit the trucks. He takes out two of them before they could fire a single shot despite both of them already having their fingers on the triggers. From a distance he nearly throws one of them through a truck. There's literally not a single strength feat from CW, IW, or Endgame that compares to that one feat.
While all of them began shooting in the direction where the guy came from, he ran around behind them and strikes a guy hard enough to send him and his truck mounted gun flying, again there isn't a scene from his other appearances that compare.
Without looking he causes a man to flip and knocks him out after throwing half a door that he cut off at him. T'Challa's claws struggled to cut through a random rusty stick Bucky picks up. He has no such issues in his movie.
Not once in his other appearances did he fight with the skill, strength, and intelligence shown in that one scene.
The biggest thing T'Challa got to do in a fight in CW was beat Hawkeye, the Yamcha of the Avengers after getting held back by him in a fight that lasted too long. I would be more impressed by the arrows to the face if it were the same kind as the ones Hawkeye used in Avengers or AoU and not the low grade explosive arrows in CW that aren't meant to hurt anyone, only distract them. Remaining conscious from the explosion to the face that he got in BP was much more impressive especially considering Aquaman was hit by what looked exactly like the same weapon Killmonger used but got temporarily knocked out while T'Challa only suffered from his senses getting overloaded.
The only thing the Russos seem to got right was running and that's it. Where's the strength? Strategy? Etc.
T'Challa took much stronger hits in his movie than getting hit by Thanos sword. Klaue destroyed two cars with his sonic cannon. T'Challa gets hit by it and the most that happens is a small portion of the suit gets destroyed. The rhino hit him with far greater force than the sword, it sent him flying in the air and crashing into a rock with only getting the wind knocked out of him. Finally during his final fight with Killmonger, T'Challa got hit by a train when the suit's protection got deactivated and still got up to fight.
When Thanos broke Cap's shield he was pissed off and doing repeated heavy blows to it. T'Challa would've been dead or seriously wounded if he was hit by one of those blows.
I'm not sure where you got CJP hated the movie from, he liked it, he gave it a glowing review. His only real complaint was that it follows the Marvel formula, a big battle in the final act where the hero fights a evil version of himself and the conflict is resolved by fighting. The only time I can think of him criticizing the character is back during CW because BP goes after Bucky on nothing but a blurry picture.
Ryan and Marvel invited CJP to the set before, it won't be surprising if they bring him back for the sequel.
