Longer seasons would allow them to throw in a few SciFi oriented episodes that don’t necessarily advance character arcs. Where would SNW be if TOS didn’t have the “Arena” (Gorn) episode that was based on a completely unrelated SciFi short story?
Mirror, Mirror was a SciFi episode that not only gave us the foundation for Discovery, but cemented the evil-twin-goatee trope into pupular culture.
Space Seed (Botany Bay/Khan) was also a one-off SciFi episode. Where would the entire franchise be without it?
I really hope SNW makes room for exploring the sort of SciFi ideas that Star Trek was originally based on.
