again, the running theory is that these are the shows that wanda watched growing up in sokovia. the simplicity of sitcoms were a form of escapism while real life was no good for her. little kids didn't watch MASH or magnum PI. they watched stuff like leave it to beaver and bewitched. she's put herself in this sitcom world because they make her feel safe. she can't remember anything bad because her psyche is literally trying to protect herself from everything that's happened (and probably specifically what's happened after end game).
i fully understand why people might not be interested in watching 50's and 60's sitcoms, or even ANY sitcoms, but clearly that is the direction the show has taken. there is this weird ownership that fans have that things MUST be for them, and that's why you get all these people who are giving such bad reviews. they wanted the show to be something that THEY like and aren't judging it on it's own merits.
