They stuck that landing alright, didn’t think it was all that good up until now and I still don’t think it is that great but the landing really sets up Phase 4.
annoying though if you don’t have Disney Plus you risk missing out this set up if just followed the movies.
I'm sure they've done it like this so that you can watch the films and these mini-series won't be essential for following events along but just make the experience more complete.
So in the next films we'll have this multiverse interfering with the 'main' timeline and casual people will be okay with that because we had time travel in Endgame so what's a parallel universe or two cropping up, but if they watch Loki they'll see the *why* they have multiverses. Loki himself gets series 2 and stays in the background maybe influencing stuff that happens in the films without having to be in them directly.
Scarlet Witch - she didn't take losing Vision well and the next time we see her (probs Doctor Strange 2) she's got all lost up in dark magic, makes sense. If you watch Wandavision you get to see the downward spiral in more detail.
FATWS - next time we see Falcon he'll be the new Cap, not much of a leap as he was all 'Murica and wholesome. You can watch the series to see how that came about.
It's kind of... formulaic but I get why they do it.
