When ENT was in first-run, I stopped watching after season two. Those first two seasons were just far too lackluster for me to try dealing with anymore of it. However, I'm glad that I recently went back and watched seasons three and four. Season three was mostly strong, and season four was almost entirely great. I am disappointed, though, that it took so long for the show to find its footing. If it had been able to impress & retain audiences much earlier, perhaps it would've survived another couple seasons.
