Honestly, I was very underwhelmed. There were plenty of good moments, but I felt like the whole movie was lacking, which is a shame, because the first one was my favorite Marvel movie. I felt like a lot of the humor fell flat, and it took so long to establish "real" conflict: I could tell the early opponents weren't going to be the "main" antagonist, which in turn, made things a smidgen too predictable when things turned out the way they did. I did particularly like Yondu's fight scene (you know the one), and there were some very good character moments too. However, the post-climax scene felt overblown. And while the cameos in the first movie were surprising and fun, here, they felt too heavy-handed. Stan's cameo was pretty meta, and I applaud that though.
