Finally saw it last night with my son. Good flick, very enjoyable. The entire South Korea segment was my favorite part.
I felt the acting was very good, especially Chadwick Boseman who's understated manner made it more believable. Also thought the sister, and the General were well played. Winston Duke, the leader of the mountain tribe, was also enjoyable.
Michael B Jordan was captivating in some scenes but he also had a handful of "cringe worthy" moments. Andy Serkis was fun to watch but became too "over the top". Seemed like a different character than in Ultron.
The plot was refreshingly different than other action movies and somewhat unpredictable (until the last battle). Yes, it was preachy at points and a bit contrived but overall both my son and I gave it a thumbs up!
Can't see it being nominated, much less winning Best Picture. But maybe, as others have said, best costume design or perhaps original screen play.
