My only hard negative was the film's first fifteen minutes. I thought it was too flashy and campy. The movie settled down and met my expectations from that point forward.
What I enjoyed most were the two contrasting father/son dynamics. Yondu and Quill continued their feuding that started in the first film. Peter did see Yondu as his father but one who took him away from his Earth family. The audience is then presented with a relationship between a son and the father he never knew. Peter was initially awed by Ego's acceptance of him as offspring.
Slowly but surely, the audience sees Peter accepting which of the two prove they were the his true loving father. Then we watch Quill lose him through supreme sacrifice.
GOTG: Vol 2 has plenty of laughs. I think practically all humor was spot on. For me, humor delivery was
many times better than in, say,
Thor: Ragnarok but I will not digress for everyone's sake.
The movie has strong dramatic aspect intertwined also. Overall, I considered it as well-rounded entertainment and a solid MCU chapter.
