My problem is that in hindsight, they have this quirky, humorous gimmick that's really about enslaving dozens of people, but they act more like it's a puzzle for Wanda to solve, rather than an ongoing atrocity that must be eradicated, and the implications for her coping or failure thereof are more important than the horrible stuff being done to the innocent bystanders, and that sours the earlier interesting parts for me.
That doesn't exactly strike me as reasonable on either part. It's wholly unnecessary for the film, and it's a multiverse thing, so even if it's offensive, it's not like the film is endorsing or promoting it. It would be like the right today getting offended at Robert Jordan putting Aran'gar in WoT or the Cosby Show episode where Cliff and Theo get pregnant.
I watched the first season too. Part of my problem is just I find stuff from that period off-putting. I wasn't a huge fan of the first Captain America either, outside of the war theater stuff. And I really don't like the kind of superiority most works that relate to the present take on past eras. But with Carter, I had a problem that they did not make her impressive in her own right, just impressive for a "dame". Like her material was written by someone from the 1940s, rather than the 21st century. Either it's just her being basically competent in a sea of too-stupid-to-keep-breathing types, such as in the scene where the enemy agent is escaping and the men all chase him while Carter calmly goes directly to the lobby to trip him (Ha ha, but what even is this? Why is she bothering, instead of working privately with Stark funding? ), or else she is being held to an abysmally low standard. They think she's being impressive when she "establishes her authority" by ordering the soldier to lean into her punch, but it's just dumb and being a bully to boot. If you have to punch down at the men (and since leading them into combat does not seem to have been the plan for her, she does not), demonstrate some actual skills, such as encouraging him to take a swing and then knocking him on his ass. Beyond that, put them in their place with a citation of the chain of command. Then there was the scene, partly shown in the trailers, where she demonstrates the qualities of Captain America's shield by shooting it, to the surprise and alarm of the men present. Out of context, it seemed like what I wish they had done with the doubting soldier, Carter being utterly confident and giving a decisive demonstration of why he should not be questioning her. But in the movie itself, it was an immature reaction to the sight of Steve being kissed by her compatriot. I wanted an ahead-of-her-time asskicker and I got a stereotypical 1940s love interest (and personally, on an attractiveness scale, I'd go for Amanda Righetti, who plays the fake nurse when he wakes up in modern times, over any of the agents he actually gets to kiss for real or not in Steve's three solo films).

I wondered if that was the same actor. I suppose it's to be expected given they brought back Patrick Stewart in this, and Charlie Cox for Spider-Man 3. Especially when you'd expect McAvoy, if anything.
I've managed to get considerably clear of spoilers and leaks for most stuff in these franchises so far.

Honestly, Renner and Hiddleston gave me the highest hopes for their series, even if I have generally been less invested in their characters than Falcon, Winter Soldier, Wanda and Vision. The first episode of Loki was really slow, and I couldn't be bothered to resume watching it, especially with the track record of movie-adjacent shows on Disney plus to that point. Maybe I'll give them another try.
