Marvel enjoyed both box office and critical success in the years leading up to Avengers: Endgame. During this period, the MCU had one of the most loyal fan bases in cinema. Endgame saw the pinnacle of that success, becoming the second-highest-grossing movie of all time, making almost $2.8 billion. In recent years, there has been a stark fall-off in both critical and commercial success within the MCU. Much of the original Avengers cast is transitioning out of main roles, so some growing pains are to be expected. However, X-Men ’97 showrunner Beau DeMayo (The Witcher, Star Trek: Strange New Worlds) believes that management within Marvel must share some of the blame. He recently took to X to share his thoughts.

One of his many complaints about the studio was Marvel’s perceived lack of respect for the source material. He stated that instead of actually reading the comics, many of the execs would work from development documents that their assistants created. Assistants reading material is not uncommon within Hollywood, but it is typically used as a filtering process for executives, producers, and other key talent who will then read the best work. 

Also, remember how the Secret Invasion creators bragged about not reading the comics?

Well, this is how Marvel does it.

The assistant to the lead producer actually does all the reading of the comics, and creates a Development Doc that covers the comics and that includes…

He claims that Marvel’s “problem” is “Kevin’s Parliament”, a group of executives who lack knowledge of the source material but still give a seemingly endless stream of notes. DeMayo believes that X-Men ’97 came out unscathed because it was not prioritized by Marvel executives.

Part of @MarvelStudios problem is below. Kevin’s “parliament”. A committee of executives who give endless notes on projects, even if they are not familiar with the project. Luckily, Kevin and Parliament didn’t care much about #xmen97 so I never received notes from them. It’s one…

DeMayo appears to be an avid fan of the X-Men comics, believing that one voice alone was not enough to truly encapsulate their impact. 

Ugh, a follower asked me if I had faith in @MarvelStudios Mutant Saga and I clicked away and lost the message so hopefully they see this, but also I get asked this a lot so I wanted to make a larger post that may piss some of you off. I’m sorry in advance.

First, the X-Men are…

According to DeMayo, Marvel declined to pay for a wrap party for the crew. A tradition which he took upon himself, claiming to pay $7,000 out of his own pocket. Additionally, he stated that Marvel executives elected not to attend the premiere of X-Men ’97.

One of the many final straws for me was was Kevin and the studio leadership not attending the premiere to thank or show support for the cast and crew who busted their ass working 7 days a week for 3 years to make the show what it was.

And, also the studio declining to do a wrap… https://t.co/EQ6hHieao2

Perhaps his most controversial claim was that Kevin Feige (Black Panther, Thunderbolts) said that he would be “happier” with X-Men ’97 if fans were not using it as a “referendum” for the future of the MCU. DeMayo believes that executives saw him as a “threat’ to the current status quo. X-Men ’97 currently has a 99 percent rating on Rotten Tomatoes and a 91 percent rating on Popcornmeter, their audience-based metric.

Yep. I was told this in a phone call after Ep 5 premiered. I asked the exec if Kevin was happy, because stupidly I still wanted to help the studio out.

There response was a long pause, and then I was told that he’d be “happier” if fans and audiences weren’t using it as a… https://t.co/qmhE8vyHMa

Some fans in the replies to this post appear to agree with Demayo. 

So it sounds like Kevin Feige isn’t happy if his name isn’t attached to a particular project. X-Men ’97 was really good. The culture at Marvel Studios sounds toxic

Just modern Hollywood man. They are hell bent on destroying anything doing good or with hope… we’ve seen it many times over the last 5 years. Theyre in full collapse.

Whether or not Demayo’s claims about the MCU are true, the decline of popularity of Marvel is undeniable. According to ScreenRant, Marvel’s Phase Five has been its least successful in terms of total box office. Phase two also contained six movies and grossed approximately $1.6 billion more. Even when the MCU was in its infancy, Phase One grossed approximately $200 million more than Phase Five. Phase One also contained six movies.
