Saw the movie last night and really enjoyed it. It definitely has a different feel to the other MCU movies so far and I loved the characters and design of Wakanda.
However, there was one thing that distracted me and took me out of the movie, and that was every time Black Panther was on screen. CGI is noticeably a step down from Civil War with Black Panthers fight scenes looking weightless and bendy. What made the effect worse was the unrealistic camera movements swirling around them during these scenes, they just had no presence to them. They looked like the kind of tacky CGI you'd see in older movies which was really at odds with the tone and look of the rest of the movie (all of the hyper loop fight looked particularly bad).
Even though Black Panther was also CGI in Civil War, there he looked completely real and his fighting and movements looked weighty and realistic for the most part. I didn't even know he was CGI until I watched something about it online. After the movie I rewatched some of Black Panthers scenes in Civil War to be sure, and the difference is quite surprising. It probably doesn't help that I much prefer the Civil War suit either.
Overall (for me) I'd rate it a little lower than I expected due to weak CGI which I think is going to age badly. My top 5:
Winter Soldier
Civil War
The Avengers
Homecoming
Black Panther
