What is good writing to you? I don't apply the Oscar/Emmy/Golden Globe metric to CW shows, they are like fast food - easy to get and tasty but ultimately not good in the long run. I wish they were better, it can be done but most shows i consider with better writing are on Streaming Services and have much shorter seasons, forcing them to write tighter and cut superfluous elements like the villain of the week.
With broadcast TV it's a different animal and having a show with only 3 cast members over 22 episodes can't work - it would be boring and no amount of good writing could fill 22 episodes without starting and completing several storylines.
I'm trying to come up with shows that have such a limited cast like the Superman movies (Reeves + Daily Planet group vs. Luthor and a few sidekicks) but can't come up with one. Every TV show i know had an ensemble cast be it a comedy, crime or drama show. There's always the lead character and 2-3 close supporting characters and a wider recurring cast group - that's how it's done since TV shows existed so why apply a different metric now to Superhero shows?
