The problem with this show is the lack of a coherent arc really. It really does jump all over the place. Add to the fact there are terrific differences in acting standards and you end up with a mess. If you compare it with say Gotham it simply hasn't managed to improve Season after Season. In fact the latest season is probably the biggest mess. To be honest I simply think they set it too far back starting with Superman's Grandfather was a mistake & I think looking back the show runners will realise that.
