I don't say this easily, but the Nostalgia Factor is real. People like Picard Season 3 (including myself) because, at least to some extent, it makes them back to TNG. People like SNW (including myself to a lesser degree) because, at least to some extent, it makes them think of TOS.
As far as Alex Kurtzman, he's the new Rick Berman. It's not him, it's the Showrunners underneath him who make the difference. Let me put it in Star Trek terms: Terry Matalas is the Captain of PIC. Akiva Goldsman is the Captain of SNW. Michelle Paradise is the Captain of DSC. Mike McMahon is the Captain of LD. I don't know who the Showrunner for PRO is, but you get the idea. Alex Kurtzman is the Admiral. He oversees and rubber-stamps all of it. If someone wants Terry Matalas kicked upstairs to where he's overseeing everything, that means he becomes less hands-on involved.
So by putting Terry Matalas at the top, you lose a show where Terry Matalas is in the trenches. To people who want him to be the "Admiral", that's what you think you want, but you actually don't. He's better off as the "Captain" of his own series.
