It started off good, but then the rap thing came in. Jesus, Wakanda is a different country. They have their own traditions and culture. They're not "woke brothers". They're extremely racist, xenophobic and just plain nasty. That's one of the major aspects of the BP mythos. Anyway, apart from that, it was a cool trailer. The CGI is obviously unfinished but eh, I don't worry. All in all, I'm looking forward to it, but I'll expect to hear more. If it's the Hudlin "we were Godz" version, I'll be dissapointed. If it's the Priest one which points out the obvious flaws in ther society, cool.
PS: As for Wakanda, of course it looks high-tech. That's the way it's always been. Going back to the Kirby run even. What the hell does Jungle Book have to do with it?
