Honestly the humor wasn't really a problem until Avengers. IM, TIH and CA: TFA were all pretty balanced humor wise. Thor had a little too much humor, but that mostly came out of the fish out of water aspect, with the exception of Darcy, who is kept at a small dose. Whedon overdid. He took Tony, who was a wisecracking, entertaining, but tortured character and made him into a reckless butthole quipman. Made Cap into a grandpa. Turned Black Widow into a toned down Buffy, which isn't bad all by itself, but with BW, the quips seem out of place amongst the spy organization and contrast a little with the all business SHIELD Agent from IM 2. I feel like Joss could have eased into her more emotional side more carefully. Bruce is fine, but comes off more nerdy for some reason in Whedon's movies. And having Loki defeated via joke just took away so much of the drama of the situations in the movie and thinking about it after it comes off as lame Then Tony thing creates a problem though because Shane Black for whatever reason decided to try and match Whedon's comedy by continuing the Tony butthole quipman trend, but takes Happy Hogan down with him and even throws a joke into the villain. And it's made worse by Whedon again by AOU, where he increases the Tony reckless aspect even more. And Ultron is just a little much as a quip machine almost literally. Along with other characters. Civil War Tony feels so much more like the character than Whedon's version. It's why TWS, IM and CW are up there with TDK in quality. There's comedy and humor, but it's character based and not overdone. Heavier comedy works fine for something whimsical like Ant-Man and GOTG, though I do feel they overdo too it a little too much. Have a very great day!
God bless you all!
