Rumor is Chapek was willing to let this show be TV-MA, but Iger is non-committal about that so far and meetings are still being had to determine how far they will push it. Unfortunate if true.
That was definitely the thing I had grown to like most about Chapek was his willingness to let the Disney brand finally grow up going forward, but with Iger back, things will probably shift back to how he viewed the company and he was not fond of Marvel or any of the core brands having mature/R content (outside of Deadpool 3, which he did comment on and commit to as R all the way back in 2019).
If this carries any weight, we could quietly see the Marvel Zombies series shelved (or toned down).
