Season 3 did have a couple of cringe worthy episodes/moments, but it was great to me. It was the first time since the dominion war that we had a proper story arc. When enterprise was first aired, I don’t actually think I watched it properly until season 2 - that’s when I felt they were making it more “Star Trek” and less something new and different. (Which always fails if you don’t look after the older fans too) Minefield and Regeneration were awesome. Our first taste of the Romulans and Borg in one season! Season 4 was definitely very strong. The mini-arcs, I loved. I wish they did this more before.
