Star Trek is and has always been primarily based on relationships and character interaction. In the grand scheme of things the setting is just that...a setting. People will never get tired of the way a diverse set of crewmembers interact with one another or the challenges they face; even if it is a challenge you have seen another crew handle. It's not the story but how it is told that makes it fresh.
I think Voyager and Enterprise show this simply isn't true. Audiences aren't exactly eager to stick around and watch the same thing over and over but told in a slightly different way.![]()
But wouldn't you agree that those two shows had the two weakest crew dynamics in Star Trek? I thought the Enterprise cast was particularly drab aside from T'Pol and Trip. Voyager was just kind of meh and I think they suffered from Star Trek saturation more than repetitive story telling. The criticism for both of those shows was the writing. I stand by the thought that good writing plus a character you can emotionally connect with can overcome a story that has been told before.
