I'll probably rewatch it at some point (I generally do not rewatch or re-read things unless a significant amount of time has passed). I had recently finished watching TNG and DS9. I never really watched them much in the 90s, just whenever we caught them on TV, in fact I think TNG was the only Star Trek that I had ever seen in the 90s. So once I was done with my TNG/DS9 marathons I needed more of that. Voyager failed to grab me so I started Enterprise.
One of the reasons I loved it so much, instantly in fact, was that it felt different and fresh. Suddenly we weren't on the best ship in the galaxy with the best and smartest crew that never really makes mistakes. It had a real sense of discovery, it wasn't just about the viewer getting to know the characters, it was also them getting to know the universe together, on a meh ship (compared to other civilizations), without infinite resources to back them up. There was also a sense of danger that felt real throughout the show, not just in the beginning.
As for the season 4 fanservice, I take that as an attempt to view back the trekkies that quit because of problems with the canon or that it didn't feel like Star Trek to them. And they probably knew it was going to be the last season so they tried to wrap things up. It did for me what a lot of people got out of BSG, but without the constant dread that made BSG really hard to watch, especially more than a couple of episodes at a time.
