Saw it twice and it is top 3 for Marvel movies for me. The pacing was great, Wakanda was beautiful, and the characters really got me into it. Outside of disliking the final fight between BP and Killmonger I just don't get why T'Chaka left his bros body. If youre going to go alll that way to murk someone why would you leave his body for his kid to find. I know he said that Erik was the truth he wanted to ignore but c'mon now. Movie was great though, and while it wasn't exactly an origin story it introduced Wakanda and a lot of characters and didn't have any moments (to me) where you're wondering how much longer it is gonna last
He probably didn't expect Erik to connect the dots and ddedicate his whole life to vengeance.
Maybe he wasn't aware his brother gave his son so much game about Wakanda.
