If I understand things correctly, even when an episode is credited to just one or two writers, it's not actually written by just by those two people, it's still put together by the entire writer's room, and I believe the showrunner's also give it a once over to help keep things consistent. So even if an episode is credited to Kurtzman, it was still worked on by people like Micheal Chabon and Kirsten Beyer.
Yes, that's basically right. The whole room breaks (outlines) a story together, then it's assigned to one writer or team to script it, then it's revised with input from everyone in the room, and then the showrunner does a final polish of every script to ensure consistency of tone, character voices, etc. (Even before the modern writer's room system, Roddenberry usually did a final script polish on every TOS script, although I believe the final draft of "City on the Edge of Forever" was D.C. Fontana's.)
It's something I find a bit lacking for the Discovery, as it looks way more advanced then the original series Enterprise.
It
should. The makers of TOS didn't want the ship to look like something from the 1960s; they wanted it to look like something from centuries in the future, but they were limited to 1960s technology in their approximation thereof. So to be true to their intent, a modern show should strive to look futuristic by
today's standards. I certainly wouldn't mind if the DSC production design retained more of the aesthetics of TOS -- the use of shapes and colors and such -- but it only makes sense to modernize the tech.
People complain about the "anachronistic" use of holograms in DSC, but I recently noticed that the 1968 book
The Making of Star Trek, which was written with the cooperation of TOS's production staff, mentioned that the
Enterprise's recreation deck was supposed to include message booths that could project lifelike, immersive 3-dimensional images so that the crew's families could send them messages that would look like they were really there in the room. So the TOS
Enterprise was always
meant to have holographic communication; they just never managed to depict it onscreen. (I wonder why, though. It would've been quite easy to simulate a lifelike hologram just by having the actor there in the room, and using a simple jump cut to make them appear or disappear. And we saw similar things done with Landru, Losira, etc.) Plus the ship did have a holographic rec room in TAS: "The Practical Joker."
Another factor in Disco having so many producers listed in the credits is the behind the scenes drama going on resulting in so many of the producers initially hired leaving, replacements being hired, and they leaving and getting replaced. Their contracts specified they had to be credited for the whole season, and so we ended up with over twenty credited producers and execs.
I don't think that's quite true. I do recall seeing some names come and go over the course of the season. And as I said, fewer than half of those 20 producers were involved in the creative side; many of them were financial partners or production executives of the various companies connected to the production. Many shows these days have a similarly huge number of credited EPs; it's hardly unique to
Discovery. The only reason DSC is the first Trek show to have that many EPs is because it's the first Trek show to be made in the modern era when such proliferation of EPs has become commonplace. The expense and complexity of modern TV production means that shows generally need to have multiple production companies and financing partners involved, and the people in charge of them all get EP credits in return. A lot of the time, the credit just means that the person makes money off the show.
