I would've liked Gotham more if it was just a noir police detective story featuring Jim Gordon and some other familiar faces, without trying so hard to Batman it up. It was fun every now and then, but the novelty wore thin.
I think Krypton has more leeway. Most anything they do gets blown up in the end. Other than Zod, Brainiac, and maybe Doomsday, there's not a lot for them to screw with/up. It'd be nice if they plotted their course from beginning to the definitive end, too, instead of either ending with loose threads or drifting aimlessly from season to season like it doesn't know where it's going.
