TOS character revisits were just those few, with Scotty's episode having been one dip into the well too many, as it were. Spock and Sarek would've been alive in TNG's time and not "illogical" to include them. Although I will be the first to admit that there episodes were not that great. Uhm ... Bones' passing the torch, I could've done without, but they felt it important that the first series sequel get TOS' blessing ... what can you do, you know? But I agree entirely about TNG and, especially DS9, being entirely too dependent on the Klingons. Yes, TNG relied on that TOS staple almost regularly so ... you definitely got me, there.
I agree about the Klingons... mostly because TNG and DS9 so rarely found anything actually interesting to do with the Klingons. They took a potentially fascinating species and turned them into one-note clichés.
But TOS callbacks? That's another story. IMHO those were consistently among the
best episodes of the Berman-era series, and I wouldn't have minded more.
I'll bet any money that there's gonna be an echo chamber across the net for an 'Enterprise/Pike' spinoff series after his episodes premiere...
Even though it would be silly to do so, since Pike is nearly at the end of his mission at this point.
How do you figure? It's fall 2257 for the DSC crew. The standard understanding of canon is that Pike commanded the
Enterprise from 2251 to 2264. IOW, he's basically smack in the middle, with more years ahead of him yet than the total time that Kirk had the ship.
(Which is not to say I disagree that the April era would've made more sense for a prequel. But that ship has sailed...)
He's 45. How old is Pike supposed to be in the year STD season 2 takes place? It looks like they artificially aged him for Season 2. I don't think it would be a problem for him to pull off 35 if they wanted to.
Pike (in the prime timeline) is typically said to have been born in 2219, so he's about 38 at this point.
There's a reason Origin Stories are nearly universally hated: there's a reason it was Backstory.
Universally hated where? In super-hero universes, for instance, the origin story is often understood to be the
best story about a given character, the one that really shapes things before they settle down into formula. Granted that's not exactly the context here, but I'm struggling to think of a context that really fits your remark.
Nah, they should do a series about the USS Saratoga from TVH. I mean, as long as we're building shows around characters that all of five people in the audience know about ...
Oh, c'mon. Any self-respecting Trek fan knows who Robert April is!
Seriously, "who was the first captain of the
Enterprise?" is basically Level 1 in any Star Trek trivia contest...
The song is twenty years old.

Movies and movie trailers use pop music now. It's a thing. Usually a current one though. Unless it's Guardians of the Galaxy.
And? In pop-culture terms, 20 years ago might as well be last week...
