Just finished the second season of ENT, as in right now. Most of the season wasn't too great, to be blunt, but then they managed to turn it around with the last five episodes:
"Cogenitor"
"Regeneration"
"First Flight"
"Bounty"
"The Expanse"
Before, I was trying to keep from falling asleep with S2. But then, all of a sudden, it's like they rediscovered their spark toward the end. Like there was some fire to it again.
