As per my title: Season 1 had some merit; Season 2 is much worse. Six stars as a nod to Season 1, which did a good job of tying together (eventually) a coherent and interesting overall story line. The Doctor Strange episodes in particular were really well done.

Season 2 however is much worse - poor writing, much less interesting story lines, and as has been noted by others, a puzzling over abundance of Captain Carter. Is this really what fans were clamouring for? At some point in the MCU series and films, someone needs to realize that pounding home the message 'women rule!' is not the same as actually having good writing and an intelligent plot. There have been notable exceptions: WandaVision, Loki are among strong offerings, but the majority, including Season 2 of What If, has been pretty weak.
