Ill go further - I am not at all excited for Doomsday. And I think that Infinity War and Endgame was the near perfect culmination of the greatest Cinematic undertaking of my 41 years of life.
30 something movies, 8 or more franchises, dozens of High Quality actors all properly managed to string together a complete narrative that rarely missed. Sure some of the standalone films over the decade missed, but they typically fixed mistakes or learned from them. They had series change directors, actors, all while still maintaining an overall vision (no pun intended) that was great and added characters on the fly without it feeling unnatural. Black Panther was only in about 20 minutes of Civil war buy came out of that movie in a way that he was a star character up there with the Original Team. Shit, he only had his 1 movie, and then maybe 20 more minutes of screen time in tInfinity war and endgame. All in all that character had maybe 2 and a half hours of screen time and became a top Marvel character. Strange and Antman were tied in well too, and the Guardians slid into the Avengers on the fly perfectly.
the fall of marvel post Endgame will be studied someday for the way in which they have completely failed every project since. How they took a good thing and oversaturated it. How they introduced new threads and characters that disappeared or were never mentioned again. How they actively talked down to, hated, and blamed their own customers for their failures. Chadwick dying was a major blow that set them off at a complete disadvantage coming out of Endgame when TChalla was set to become a major leader of the franchises. But even then not much would have changed - BP2 would have been better but they have siloed every franchise since so its not like he was missed elsewhere.
they fumbled so bad they brought back RDJ as a hail mary and are going to lean into the Multiverse shit so heavy because they have no other choice, they ruined their only beloved characters and pushed their shitty political and Diversity initiatives so hard and they fell so flat that they don't have a single marketable property to sell this dump of a film.
F4 has to literally end up the best movie ever, with this cast being so well liked that they can anchor Doomsday. And I just don't see that happening in a movie set in an alternate dimension that ends with them losing to Galactus and fleeing to our reality.
All they had to do was give Bucky the shield, Make She Hulk without actively shitting on and ruining the Hulk, and had some level of oversight on Taikka in thor and the writers rooms on Wanda and Multiverse of Madness and you would be looking at the highest grossing Marvel film ever. Instead its going to limp out like a popcorn fart when no one wants to see Evil RDJ vs a bunch of nobodies.
