The Arrowverse quickly turned into just more CW Dramas.
Flash by the end reolved so much around Cecile "the hardworking supermom who is struggling to balance her superhero life and raising a family". Not an exciting show.
Funny enough, remember a line from Big Bang Theory that ripped Smallville and applies now to the Arrowverse too.
Sheldon was talking about wanting closure on stuff, and mentioned Smallville helped him get closure easily by declining in quality by the end so it was easy to not miss it.
