Sorry I'm coming to this a little late. I wanted to weigh in on the series so far. I'm going to be critical, but please don't mistake my criticisms for "hate." This show is subject to the same critiquing as any other work of fiction. I'm going to try not to get too bogged down with the minutia of how "believable" it all is- after all, this is a universe built on super hero comics. I definitely take it all with a grain of salt as to living in the reality that has been set up. But we've also had two dozen MCU movies that have generally established the rules and tone of these connected works, even if there is some variation. I think it's fair to judge the "reality" of this show by comparing it to how it fits in with those previous works, as well as on it's own merits.
Okay, here goes.
I don't find the sitcom parody aspect particularly interesting. This isn't just my personal preference, but from a critical point of view, we've seen these types of parodies done to death in other TV shows and works of fiction over the last several decades. It isn't new or fresh to me, despite the tonal shift from how these characters were previously presented in the MCU movies. While the actual recreation of the different sitcoms is fine, it's not really exceptional to me. It's a fairly easy format to recreate, and some of the lighting and camera shots don't quite have the right look of the sitcoms and the era of television they were recreating. I realize I'm nitpicking, but others have commented on liking the recreations, so I feel it's fair to opine on the detail of it. The writing is also simple parody, and didn't offer enough to me to be interested in these full episode recreations. Maybe because I've seen decades of sitcoms, I've become jaded on seeing the same jokes and tropes regurgitated once again, but I still think they need to do something more with the premise in order to retain an audience's interest. It feels like lazy writing to me. And it just feels shoehorned into the MCU reality. A little of this goes a long way, and it's already been a lot. If the idea is to create a mystery by throwing the audience for a loop, having us wonder why these characters are now so different and in an obvious fantasy world, it really isn't effective to me. We all knew this wouldn't be the reality of this entire series, so it had no impact when it was revealed. The supposed dramatic elements when the sitcom trope is broken within Wanda's realty don't really work for me because the sitcom reality is too farcical. I can appreciate when comedies offer dramatic moments, but it doesn't always work (side note - HBO's Barry is a good example of a series that's been able to effectively swing widely from comedy to tragedy).
I do think Olsen and Bettany do a great job with the material, as does Hahn, and I appreciate their acting ability and getting to see a bit more of their range (though I've seen more of Bettany and know his range more than Olsen). And giving these characters more personality makes them more personable. But it's a lie, because the characters of Vision and Wanda really haven't changed. These are just facades. It doesn't add to anything of the personalities of the actual characters. Unless we see them retain some of these traits at the conclusion of this story, the characters have not developed in any appreciable way.
Moving on: now we have other "real world" characters. But Monica Rambeau is not an interesting character to me. Maybe it's the actress, maybe it's the writing, or a combo of both, but I'm not interested in her. It's probably also because the character has barely been in the MCU, only seen as a child (who, honestly, wasn't very good or interesting) in Captain Marvel. Even the mother of her character doesn't evoke strong feelings, being a side character in just one film. It's evidenced to me by the lack of emotional impact when it's simply announced that the character died offscreen. They didn't even tie things together by having the character actually pass away onscreen - it's just a footnote. Monica, who we're aware of in her adult incarnation for the first time, simply moves on with barely a tear shed. The show could've spent more time on her story and cut some of the sitcom parody material.
Since I've rambled on a bit, I'll wrap up this part of my comments here. Basically, I'm not getting a strong emotional draw to the characters, and I blame that mostly on the writing. I still am interested in Wanda's trauma, and how she broke from reality and apparently created an entirely false one on her own, using a real town and real people in her delusion. I'm hopeful we'll get more of a connection to her "real" character in subsequent episodes. But if we just keep popping back into "TV Land," it's going to feel like we're treading water, that the show is drawing out the story just to fill eight episodes (or more, if this happens to extend into a second season or more).
