I liked the first season, tolerated the second, and season 3 is challenging not so much my ability to suspend disbelief but, I don't know, my ability to absorb corny dialog maybe...
Go watch Legion if you haven't seen it:

It's genuinely good. It's the X-Men universe rather than the MCU... but Disney got control of that and appears to be on track to merging them. Legion in particular may actually be somewhat relevant to WandaVision.
I didn't enjoy the 2nd season as much as the 1st but it was still quite good. I think the 3rd season was the best. It got wrapped up in a very strange but also satisfying way which wasn't what I was expecting from it.
