I don't think they're making too many movies at all. How is 3 or 4 movies spread out in a YEAR too many?
I think people are wrongly attributing fatigue of SHITTY Marvel/super hero movies with overall fatigue of the genre as a whole. Even as an avid comic book reader and fan of the MCU, I"m tired of watching a shitty product that could EASILY be better than what it is, but that doesn't mean I'm tired of the genre itself.
Look at the timeline. There were individual good movies before 2016 (like Iron Man 1, Winter Soldier, GoTG, Avengers, etc.) but, I would say that Civil War is where things really started to kick off and come together as an actual cinematic universe.
Captain America: Civil War May 6, 2016
Doctor Strange November 4, 2016
Guardians of the Galaxy Vol. 2 May 5, 2017
Spider-Man: Homecoming July 7, 2017
Thor: Ragnarok November 3, 2017
Black Panther February 16, 2018
Avengers: Infinity War April 27, 2018
Ant-Man and the Wasp July 6, 2018
Captain Marvel March 8, 2019
Avengers: Endgame April 26, 2019
Spider-Man: Far From Home July 2, 2019
Most of these were successful movies and were clearly building towards something. There's no fatigue if you're delivering quality.
Post End Game is where it fell apart.
Phase Four[69]
Black Widow July 9, 2021
Shang-Chi and the Legend of the Ten Rings Eternals September 3, 2021
Eternals November 5, 2021
Spider-Man: No Way Home December 17, 2021
Doctor Strange in the Multiverse of Madness May 6, 2022
Thor: Love and Thunder July 8, 2022
Black Panther: Wakanda Forever November 11, 2022
We got our own real life "blip" with COVID, and the first thing we got was a movie about a character that is already dead in the MCU.
To your point about uniqueness, I'd say Shang-Chi and the Eternals were pretty unique. I thought Shang Chi was really good overall, less so for Eternals.
And then we got a great Spiderman movie, followed by 3 shitty movies that should have been bigger considering the characters and storylines involved. (I actually like Wakanda, but because of Chadwick's death, it was a movie in a weird place)
And now this year.
Phase Five[86][87]
Ant-Man and the Wasp: Quantumania February 17, 2023 SHIT.
Guardians of the Galaxy Vol. 3 May 5, 2023 Pretty damn good.
If we look at the movies now vs. post Civil War, the issue is that there is no plan or connectivity to this so-called Universe now. We got a movie about a dead character, Chinese mythology, a secret race of beings that have always been here but never bothered to help, gods of Olympus, the multiverse, teenage hero and his friends, and then Atlantis vs. Wakanda without a true Black panther......and now, skip forward to Kang The Conquerer ?
None of this feels connected, or like it's leading towards something. Shang-Chi came out in 2021...it's almost the end of 2023, so how much longer do fans have to wait to see this character again?
Marvel just throws new characters at us without building the ones they have.
Future Shit.
The Marvels November 10, 2023
Deadpool 3 May 3, 2024
Captain America: Brave New World July 26, 2024
Thunderbolts December 20, 2024
Blade February 14, 2025
There's been no real building of Captain Marvel. If she is the most powerful hero now, why isn't she in more things? Why didn't they have her do something with the Guardians? Do something in the Secret Wars series?
Deadpool will be a hit based off of its own previous success.
What has Sam as Captain America done since 2021 ? How does he fit in with Chinese magic and the multiverse? Why should anyone know or care about the Thunderbolts? And now we're going to add in a mystical/magic/monster side with Blade without solidifying any of the other characters or storylines first? There's just no organization or direction.
