Feel free to name a genuinely interesting, intriguing and likeable character on either Picard or Discovery. Characters from TOS, TNG and even Voyager will be remembered for decades to come and looked back on with fondness. I can't imagine the likes of Burnham, Tilly and any of the other no-name characters on Discovery will ever be mourned when the series ends. Perhaps if Discovery would focus on developing a few other characters they might start endearing themselves to the audience, but no - the show is 95% all about Burnham. After 3 years I still don't know the names of the bridge crew because they do and say so little. The previous series at least made an effort to integrate the bridge officers as key characters. Those on Discovery might as well be red-shirts, getting blown away in the next episode since they are so, utterly irrelevant to the series.Gee, I'm sixty-one and a big fan of TOS and DS9. I quite enjoy DISCO and PICARD. I've even come around to VOY recently.
Generalize much?
People tuned in for various reason and continue to tune for various reasons. We got Treknologists, the ship porn addicts, the shippers, the production pundits, the Trekeologists, the droolers...No one Treks the same.
If you think past Treks didn't have snazzy FX, action and emotional hysterics you didn't really watch Star Trek.
Curious what make these characters non redeeming and unlikeable?
Similarly, Picard has reduced a once-great character into a pale shadow of his former self. Stewart just looks bored of the role, and if the main man isn't interested then what hope for the rest? Another show filled with explosions, profanity, violence and misery without any characters that you actually care about.
Let's be honest, if any of the "main" characters on either of these shows were to die, nobody will care.
