I forget what the current policy is on Endgame spoilers, so I'm gonna blur these two out just in case.
1. I was honestly disappointed that Captain Marvel wasn't in Endgame all that much. And even during her few scenes, she didn't do a whole lot besides blowing up Thanos' ship, I felt. It just seemed like her role in Endgame didn't live up to the buildup she had been getting, to me.
2. I personally found Yondu's death, and the proceeding funeral, in Guardians of the Galaxy Vol. 2 to be a bit more "emotional" that Tony's sacrifice and funeral. Don't get me wrong, Tony's was still very, very well done and quite moving, but Yondu's had me on the verge of bawling my eyes out the whole time.
