That word "homework" gets on my nerves and I don't think I can fully articulate why. I guess in a way that's what a pet peeve is, when you can't quite explain why it annoys you. I think there are reasons I have yet to articulate, even to myself, but I will try to articulate it at least a bit.
They're referring to watching TV and movies as work they're being forced to do in order to watch more movies and shows. They're upset that a group of movies and shows are connected and build on one another. I think they're fundamentally viewing the MCU in a different way than I do, they're viewing each movie and show as a seperate entity while I view it as one long series. To me it sounds as silly as complaining "I want to read Harry Potter and the Deathly Hallows but it requires me to read six other books for homework". Obviously each book in the series builds on the previous ones. Maybe watching a long franchise consisting of movies and shows isn't for everyone, if it's a problem for you to watch every entry in the series, maybe just don't watch this franchise.
I sort of get where some of these people are coming from. They want to see Marvel movies in theatres but some of the movies are connected to series they can only watch if they subscribe to Disney+, which they don't want to do. But watching movies has never been free. Even if the movies weren't connected to Disney+ shows, they're still connected to movies you have to pay to watch somehow.
