I finally watched it. I think the first was better, but one was predictable and this one was just forgettable. The villain was goofy and not very interesting IMO. I think, like the first, I really like the concept of Wakanda, their tech, characters, etc., but the movies aren't up there for me. I thought that the Midnight Angel armor was awesome though!
The other problem I have with super hero movies is that in this one Wakanda is in trouble with a possibly superior enemy and they don't ask for help. I'm sure at least one of the Avengers is around. I mean Thor isn't doing anything and he's most likely on Earth then. Marvel always conveniently says "Oh all the other heroes are busy with something...". I think Thor would make short work of that dude with leg wings. It's like in the first Avengers movie, the glaring error (obviously due to licensing) was that New York was under attack and Spiderman wasn't there.
