I genuinely loved Enterprise when it was airing, but I still knew it was flawed. Much like Voyager totally wasted its entire premise and instead tried to be TNG-lite, Enterprise somewhat wasted its own potential with run of the mill storytelling in the first couple of seasons.
Granted, there's a few gems in those first couple of seasons. The Vulcans were different from what we expected, which made them interesting. The Andorians were certainly standouts with Shran stealing every episode he was in. They even managed to make a sequel to First Contact and make the Borg feel threatening for the first time in ages.
But they also got bogged down in the whole temporal Cold War. Plus, they just couldn't resist the low hanging fruit that was the Klingons. Again with the Klingons. All that, combined with a great many mediocre episodes, I can't blame alot of fans for abandoning the series.
What kept me going was a genuine love for the cast, or atleast the ones that actually got interesting storylines. Sorry Hoshi and Travis.
With Archer, I saw exactly what they were going for, and I liked it. The boy scout that was in over his head, but with a big enough chip on his shoulder that he wouldn't let anyone hold him down. Out of all the Captains, he's the only one who feels like an explorer, who's not afraid to show that he still has a sense of wonder about the universe he's seeing for the first time. I like Captain Archer. Alot.
Then you have the Ying and Yang of Trip and T'Pol. I wasn't sure how I'd feel about those two when the show first started, but by the end, they were just as important to me as Archer. The charming southern "good ol' boy" was a act I was sure I was going to hate. But, he won me over.
T'Pol was the same. And admittedly, I was a little slower to warm to her. But, just as she warmed to the crew, so did I with her. Her emotional journey throughout the series was one of it's highpoints. Watching the loyalty she formed to Archer, and he to her, was heartwarming. TATV is an about trash heap of an episode, but when Archer went back to hug T'Pol......
While the rest of the crew certainly didn't get anywhere near the level of character development as the "big three," I liked them all. Reed with his stiff upper lip British attitude that slowly thawed. Phlox with comedy and warmth of character. Hoshi with her initial fear that turned into courage. Even Travis with his naive, if not optimistic outlook.
Thankfully, the show seemed to turn a corner with its third season. I enjoyed how they took this bright and sunny crew and took them down the road of darkness, but they were still able to come out the otherside having learned a great deal about themselves. The weight put on Archer was especially good. Here we saw the boy scout pushed past his limits to nearly the breaking point. The boundaries he had to cross seemed to forever change him in a way few Captains have been changed. But, he was still able to hold onto that boy scout attitude, if only a little.
The 4th season is where we finally were starting to see the potential in the shows setting. Indeed the beginnings of the Federation and the Romulan War is one of my favourite era's of Star Trek lore.
But alas, it was cut short before we were truly able to explore it.
To this day I still hold out a sliver of hope we may someday explore that era again. To see the Federation forged in fire. Humanity pushed to the brink by the Romulan War. Who knows, maybe someday in someway.
TLDR: I liked Enterprise.
