I dropped Arrow (too formulaic these days), Legends of Tomorrow (way too on the nose about being a comic book show for my tastes), never watch Supergirl live (wait until it hits Netflix) and I wasn't crazy about Black Lightning after the first episode so I didn't feel a strong urge to watch any of the following episodes. The only CW DC Comics show I watch regularly now is The Flash, because it has that perfect balance of being "grounded" but also still a faithful comic book adaption. Although, it helps that the big bad this season isn't another speedster, otherwise I probably would have dropped that too.
Now my CW viewing is limited to Flash, Crazy Ex-Girlfriend and Riverdale (when it hits Netflix). I'm going to check out Sabrina the Teenage Witch on Netflix when it debuts, but I don't know about that show being as dark as Riverdale is. To the best of my knowledge, the Sabrina reboot is the first TV/movie show that I've grown up with to be rebooted (besides Jumanji, I haven't seen that yet), so I don't know how I'll react to it.
