I have to say, I enjoy what they did with the Hulk (besides showing his butt). Also, the intro to the movie was one of the best I've seen in a LOOOOOONG time.
The buddy cop thing is definitely present. Albeit, I kinda enjoyed seeing Bruce Banner interact with Thor than Hulk. Hulk and Thor was still really fun, but Banner's awkwardness and constant threat of becoming the Hulk is always way more fun for me.
They also got the different personalities for the Hulk done flawlessly this time. It felt like a proper comic Hulk. Oh, and how can I forget that Stan Lee cameo? Excellent, per usual.
I take back what I said about Valkyrie from about a year ago; I really enjoyed what they did with her. And once she got her actual Valkyrie armor on? That's when I finally was happy.
Loki was great, per usual. Really enjoyed the character development for him this time around. Jeff Goldblum as the Grand Master was just excellent casting and I enjoyed his preformance. Korg was a surprisingly fun character as well. And I gotta say, I'm glad they had the guts to actually destroy Asgard in this movie. Really looking forward to Infinity War now.
