Rant: Adam Warlock, the man who beat Thanos in the comics, doesn't get to be in the Thanos storyline in the MCU.
A totally unnecessary change.
Rant: Mar-Vell gets changed into a woman and his entire legacy as the original Captain Marvel who dies of cancer and passes the mantle on to his ex-love, Carol Danvers, is forgotten.
An even worse change.
Rant: Hank Pym and Janet Van Dyne are still not in the Avengers in the MCU and have been reduced to aged side characters, while Scott and Hope, two characters who don't even belong in this story, get to be the MCU Ant-Man and Wasp without having earned the right to be there.
Hank and Janet have been in the Avengers comics for 50 years and have been in nearly every single Avengers storyline ever written. Even if you're not a fan of the comics and you only know the films, I don't see how you can find anything that justifies this.
Can we please retcon the MCU at some point and put Hank and Janet in the Avengers and get rid of Scott and Hope once and for all? Every year that the MCU continues this, Hank and Janet keep getting shut out of the Avengers not only in the movies, but in animation and the comics as well.
Rant: Peter Parker is still a punk high school teenager in the MCU due to Hollywood's disturbing fetish with always making him jailbait.
Peter has been an adult in the comics since the 1970s. Can we please get an adult version of Peter in the MCU, and one that isn't animated and that takes a back seat to Miles Morales?
Rant: From what I've heard about Endgame, this version of the MCU Avengers storyline will probably end soon, and good riddance. They did some stuff that will hopefully mean recasting of certain roles will happen.
