I've found some of the individual episode OK, but the whole arc of this season has been kind of a mess.
I thought I was behind, but apparently the last one I watched, the VR Alex as Supergirl one, was the latest.
The stuff with Alex as Supergirl and using it to deal with her father's death was OK, but all of the stuff with Kelly and William really hurt the episode. I hadn't minded them up till now, but with this one when we got a significant part of the episode that was just them, I realized just how fucking boring and bland they are. Every time they showed up onscreen, all I could think about was how badly I just wanted them to get back to Alex.
