I like the show a lot. Let me tell you, one of the biggest problems I had with Kirk and crew was the never changing, despite agin......
That is, definitely, one of my big criticisms of the films. For TMP, Gene promoted Kirk to Admiral (technically, Rear Admiral Lower Half, forgetting he'd established Commodores during TOS), but rather than leave Decker in command of the ship while he commanded the mission, he was made Captain again, just like in TOS. In TWOK, Sulu was supposed to have just gotten what would be revealed to be the
Excelsior, but Bill didn't want another Captain in the "second-stringers" (Nimoy was okay, he was a close friend), so he kept blowing the takes where that dialogue was and they ended up having to drop that shot. When there was a chance they might all move on to the
Excelsior, it ended up being just a replica of the
Enterprise again. Sulu finally got his own ship on their last outing as an ensemble, when it almost didn't matter any more.
We should've seen the majority of the senior staff moving off the
Enterprise and on to other assignments over the course of the films. They kept setting it up, but then not paying it off. According to the ancillary material, Uhura ended up head of Starfleet Intelligence, Hikaru Sulu also made it to the Admiralty, Saavik commanded the
Enterprise-B for a while after Harriman and Demora Sulu before retiring and marrying Ambassador Spock. But that's the novels. We should've seen that on the screens big and small.
