Not only do I remember negative fan reaction to Star Trek the next generation, I remember negative fan reaction to Star Trek the motion picture. Specifically, to the new klingons. "How dare they change the klingons?" The more things change..
Ditto. And I too did not like TNG at the start. Out of the group I hung with that were Star Trek fans, I was the only one who stuck with it; and honestly, I kept hoping for a good episode but was constantly disappointed. I didn't think it became at all watchable until a few episodes into season 3.
The first episode I can say I honestly enjoyed was TNG S3
Yesterday's Enterprise. I will also admit that
Best of Both Worlds had me hooked at the cliffhanger; and that's when some of my friends who had given up on TNG started actually watching the series.
That said unlike TOS, honestly the majority of episodes I can watch and rewatch and never be tired of. When it comes to TNG rewatchability, out of its 178 episodes, there's probably about 25 or so that I find rewatchable.
I also found the JJ Abrams Star Trek films a real breath of fresh air after the TNG feature films, with the possible exception of
Star Trek: First Contact.
The latest new Star Trek series,
Star Trek: Strange New Worlds is exactly what I had hoped
Star Trek the Next Generation would have been back in 1987. It's exactly the type of Star Trek. series I've wanted since TOS was canceled.
