I liked it a lot, much more than I expected. A beautiful look, and less reliance on a predictably violent third act which mars a lot of the genre, imo. Closer to my idea of what a sci-fi/superhero movie should be.
An obvious attempt to elevate the status of Africa, it uses the natural beauty and native design elements to very good effect.
Update- my wife saw it with a granddaughter. She is very down on superhero movies as a rule, but she really liked it. I guess that says something.
