It's fine for me, but I think it's generally risky. They're going up from three "Phase" main releases in 2017-2020 to eight-to-eleven in 2021, depending on Ms. Marvel, She-Hulk, and Moon Knight.
That's a big leap to ask general audiences to take, as well as being a bold assumption for all general audience households to get Disney+. I know it's a meeting move: make it essential so people buy, but that's obviously a risk because if it doesn't pay off, you have essential content people aren't watching. While I'm sure Disney+ will be a success, I know there are friends of mine who will go to the cinema, but aren't the type to bother with a Disney+ subscription and watching those shows.
I also feel it undermines the special nature of the MCU "Phase" instalments. Currently, there's a lovely pattern - watch the TV shows for the day-to-day stuff, and look forward to three special moments a year with major MCU instalments. But now it will just be constant "major" instalments without the variety to make the idea of a "major" instalment excitement. If everything is major, then nothing is.
Plus I find the treating of these shows as the same level as the films weird. Something like WandaVision is a more excusable TV name than film name. Loki is a more excusable TV instalment than film instalment. But if you wouldn't make a film called WandaVision or a film about Loki, then don't make something equivalent to a film that is called WandaVision or about Loki. It makes the MCU feel like each instalment is less important, they're telling weird bonus stories in the supposedly important slots, the pens usually reserved for big next instalments in film trilogies.
I don't know...
