Great, but for the secret-keeping

Rating: 10/10 (4 March 2018)

It was mostly good, the action, acting, effects were all great, and the story was... mostly good. And as a history nerd, I love that Black Panther can pique the audiences' interest in the under-studied- but fascinating- African history!
The story's logic, though, fell short regarding secret-keeping of Wakanda's technology:
-Why didn't they take Killmonger back to Wakanda after his father died? Wouldn't leaving him abandoned make a secret-revealing nemesis out of him? (Also, where's Killmonger's mother? Would she also have known about Wakanda's secret but also left untouched?)
-And the big high-tech action scene in South Korea would've easily exposed Wakanda tech to the world, topped with pedestrians broadcasting the whole thing on social media!
-And the biggest issue is Jabari! For millennia, they distrusted using Wakanda tech, mildly antagonist to Wakanda but ultimately harmless to them, and yet kept in the cover-wall of high-tech Wakanda? Realistically, anytime Jabari would've had a leader or two reveal the "threatening Wakanda" to outside neighbors- and knowing the inner workings of Wakanda's defenses- build a coalition to invade, conquer and/or destroy the high tech. It seems too unrealistic that they'd remain the cranky, reclusive hillbilly cousins all this time.
But other than that, it was very good!
