I hated Enterprise when it aired!
Quite frankly, I was too ignorant to watch it back then. All it would have taken was the understanding as to why Tom Paris was on Voyager and not Nick Locarno. Producers will not spend money!
So Trek fan that I was, I had already dove into the expanded universe of Trek Lit and beyond, and had invested in countless versions of Trek history, pre-TOS. I was expecting interpretations of John M Ford's Final Reflection, Diane Duane's the Romulan Way, Margaret Wander Bonnano's Strangers From the Sky, Diane Carey's Final Frontier and so on. Producers weren't going to pay for any of that, so this was all brand new.
And then the studio stuck their oar in, and demanded that it look like the Star Trek that they were familiar with, so out went the plan to set the first season (or the first half) on Earth before the launch. And in came all those things from the 24th Century that we had been watching for the previous 14 years like holograms and replicators and transgenic weapons; if the humans didn't have them, the aliens did. Sticking in the Temporal Cold War was the ultimate mistake
When the pilot aired, I tried to give it a chance. But the nitpicky fan in me got in the way. I did a whoop of joy when they mentioned Neptune and back in 20 minutes, and I checked the Warp Scale in Franz Joseph's Technical Manual and they got it right. Then 30 minutes later, the Klingon homeworld gets put 1 light year away from Earth, with a stopover at Rigel on the way. I wound up hating the show for four years, and I tuned in regularly to hate on it.
And the most frivolous thing of all, I saw Brannon Braga's name, with Seven of T'Pol and NeePhlox in the cast, and expected it to be warmed over Voyager, a show I had fallen out of love with as it progressed.
But the last few years, I've encountered more than a few Enterprise clips on Youtube, and I've quite liked them (usually Trip and T'Pol shippers at work). It got me intrigued enough to buy the series on Blu-ray and finally re-watch it. And I'm enjoying it.
I've put aside my expectations, and can watch it for what it is, and it's really quite good, and in my view, I enjoy it a lot more than Voyager. The studio interference is still an annoyance, and I roll my eyes when the 24th Century makes an appearance. The Ferengi should never have appeared, and the remake of DS9's Shadowplay was egregious. Rather than Risa, they should have used Wrigley's Pleasure Planet or something. I'm 10 episodes into Season 2, and it's getting better though, especially when the episodes are genuinely pre-quelly.
And this time I'm looking forward to watching Season 3. Back then I had post 9-11 issues. I wanted proper escapism, and avoided drama that tackled that issue. It took me 10 years to get around to watching nuBattlestar Galactica, and I'm still reluctant to watch Die Hard 2. I wasn't in a good place for ENT Season 3 the first time around, but I think there's enough distance now to appreciate it.
