I was a moderate fan when it aired originally, but didn't care for the baseball game interruptions in programming. I liked the concept of the prequel, and thought they could have spent more time on development of characters, systems, government, the academy, etc. instead another 'space hopping' exploration', not that I didn't want that later, also. Most Trekkers, I think, prefer a more thematic set of episodes if not the serial approach. Too many stand alone episodes in the beginning only worked for missing them due to the aforementioned baseball season. When they went into reruns, btw, out of order in season and episodes guaranteed it's failure with low ratings.
Watching the episodes now, after completing DS9, I find the show more enjoyable. I tried to watch Voyager first, but honestly ever episode felt like the captain regurgitating scientific mumbo jumbo another officer suggested as a fix as she explained how it would solve the problem: Chief Engineer: "We could try mixing the subglutenate molecular infuser and connecting it directly to our impulse engines." Captain: "And that would have the effect of venting plasma gas from our nacelles and we could ignite it with phasers in the nebula. Right. Let's try it." Ugh. Tedious. Every. Single.
I skipped Voyager after the first few episodes and went directly to Enterprise. Honestly, I think I'd re-watch TOS before Voyager. I was glad to see Enterprise go to a prequel and not just 'space hop' all over the 24th century. I wasn't so sure about all the 'Temporal Cold War'. To me, that felt like a fall back for a sort of 'reboot' in case things didn't get well with the original writing (which I believe improved tremendously after the first season, and some after the second). There was only one them in the third: Xindi-and it was tied to the time travel-which I find ironic to be in the 'earliest' of all star trek series.
To me, Discovery is pretty much a resurrection of Enterprise (slightly different time, but not much). Too bad this series didn't have the strong writing from the beginning. All in all, I'd recommend it.
