It's really not even valid to judge an entire show for one season. If you stopped watching TNG after season one you wouldn't think much of it other than it being TOS with a bald captain. Buffy season one would be interesting really hit or miss. But in the short 15 episode season we got of Discovery, we got some fairly well developed characters with decent arcs. That's just going to continue in season 2 and beyond. Discovery might end up being one of the best Trek series by the time it ends. People were trying to write it's eulogy by the time the first episode aired.
