Darhk is as good as anything this show or the current DCTV universe has ever produced. He is up there with Slade and Reverse-Flash as the best villains in this universe, so they are clearly capable of doing good things when magic is involved. But, when things like magic come into play, it seems that people tend to get lazy and rely on special effects rather than good or creative writing. It happens on other shows and in movies too. If they use less special effects, hopefully they will have to get more creative and put more effort in, so I hope that they do go back to how it was in season 1. I still consider season 1 to be the best season of this show.
