Finally got around to seeing this and would rank it a solid B- as a movie, but definitely one of the best 'Marvel movies' so far. The imagery and soundtrack were pretty superb, as was Michael B. Jordan's role as the villain. I thought he was more entertaining than Chadwick Boseman, in all honesty.
The downsides: story telling and supporting acting. I just had a tough time enjoying the performances of some of the supporting cast, even though they had charming/funny moments. I also felt the movie suffered from quite a few plot elements either left unexplained, undeveloped or largely ignored.
