So I saw it, and I enjoyed it, and it is funny... but I did not enjoy it as much as the first. I'm not going to shit on the movie, because it IS good, but I'd much rather the first one... throwaway villain and all. The good thing is that this movie is a different movie than the first, but it's also the bad thing about it. I don't want to explain this point without giving away too much other than this...
Guardians Vol 1 is one of my favorite Marvel movies and I'd give that close to a 9.5 out of a 10.
Guardians Vol 2 comes more at a score of 8 to 9 for me.
Also, Michael Rooker is a national treasure.
