I agree that Black Panther is better than Wonder Woman, but I'd put them both in the same boat as 'not very good comic blockbuster movies' though for incredibly different reasons. I'd sooner watch Black Panther over Wonder Woman because at least Black Panther swings for a fence with its themes instead of trying to make a point with "see people are more complicated and killing a bad person won't end a war" and then immediately undercutting it by defeating one person to end a war.
