"The Wounded". Picard even says as much at the end. Also, "The Pegasus". Not having cloaking tech has been like a giant "Lose" button for the Federation.I request an episode where the villain was right, or at least had a valid point.
Honorable mention to "Paradise". Yes, Alixus's decision to allow her people to die was unconscionable, but after seeing some effects of society's perpetual interconnectedness, maybe she had a point, too.
How's about an episode that's just plain escapist fun?
