I'm watching through the Season 2 blu ray now. I didn't see all the episodes when they originally aired. I was never a very big fan of Enterprise. Some of the episodes are pretty good, but a lot of them are boring. I never realized there was an episode that was basically a remake of TNG's "The Nest Phase" with Hoshi. The episode with Trip on the hot planet with the dehydrated alien was pretty good, but it sort of reminded me of a cross between Darmok and Enemy Mine.
The episode with the Romulan minefield was good and the following one with the weird repair station was good too. From what I've seen, those might be two of the shows best episodes overall.
