But the overwhelming amount of complaints that I've seen on these forums about Discovery haven't been about continuity, they've been because the show doesn't match up with the tone of what the complainer considers "real" Star Trek.
You mean like a likable, upbeat cast of main characters? Yeah, I agree that Discovery is lacking something that I've found essential to Star Trek's formula. If I wanted to watch Battlestar Galactica (2004) or The Expanse, I could simply watch those shows. Now, if I want to watch something with the tone of Star Trek before Discovery, I have to watch Supergirl or The Orville.
