Definitely, do. And the movies.
I was privy to the mailing-list “jms speaks”, and he went into the whole deal with the execs, and laid down the law, else no deal.
First, it’s to be a 5yr arc. Not 4yrs, not 6, not 2, not 10. 5.
Second, no one is to change anything in his scripts, not rewrite sections, not so much as move a comma.
He kept total control of the series, kept it coherent, kept it as close as possible to his “vision” which he had in the shower (I kid you not), and most importantly, kept the suits out of it.
And it paid off. Things in the background you see in S1 would figure prominently in S3 or later.
Details, details, details…
In contrast, look at “Andromeda”. EXCELLENT first season, then bobsledding downhill from there after Sorbocles got his mitts on it. S1 didn’t spoon-feed you anything. One ep you’d hear feral kids referring to the “one-stoff”, and you had to figure it out on your own they were talking about the First Officer (abbreviated “1stOff”!).
After Sorbocles got to it, it turned into “Hercules In Space”. Barfights, warlords, shoot-’em-ups, completely dumbed down and more “action” than anything remotely cerebral. <gag/>
