I dont think the writing, last episode aside, had been good but there is a full writers room responsible for that, not just her. And even then my biggest issue has been a few of the performances, not Rachel.
To Hali’s point though it does seem like a show for the 2000s-2010s. Shows where the entire plot is just hanging haven’t really existed for a few years now or, at least in the case of adults and overcompensating etc., they’re on smaller networks and I think can benefit from not having the HBO ~prestige~ association attached to them
