I found Guardians of the Galaxy Vol. 2 to be very good and better than the original, unlike most others. There was a lot more plot and it was all about family. The action was great, the humor was funny, and there were a couple of unexpected cameos. The CGI of a young Kurt Russel in the beginning overtop of another actor worked well too.
My chief complaint with the film was that it seemed like I was watching an extended cut. I felt strongly that about 20 minutes could have been cut and coincidentally, that would have shortened the running time to just under two hours rather than 2 hours and 16 minutes. This prevents it from getting a full A.
