How about this:
My favorite STAR TREK era: 1964-1979
That way the point is made without coming across as "after 1979, there was no Star Trek". You have admitted that Star Trek does exist after 1979. There are episodes in various ST series that you liked. But what you enjoy the most is the pre 1980 era. And that's fine, nothing wrong with that. As T'Bonz stated, it's choosing the tone. Positive on what you like versus negative on what you don't like or believe in.
Unless the underlying preference is to periodically get "WTF" e-mails from people because of that tone, so the point can be reiterated, as in this thread (or this one: "What's keeping me out of the theater...")
