I haven't been able to make it past the first two episodes in the first season. It's basically like Gotham--all of Superman's villains are being established as villains for his grandfather like Batman's are for Gordon. I keep meaning to give it another shot, but it's tough to get through because it's basically a poorly written Elseworld's tale. I've heard it got better as the season progresses though so I'll force myself to sit through them at some point.
