#4. Twin Peaks
Why It Should Never Return: Twin Peaks was always destined to be a short and beautiful thing. Its appeal lies in atmosphere and carefully balanced contradiction — the coziness of a beautiful, all-American small town contrasted with the sins hiding underneath the surface and the absolute evil that lurks at the edges. The fun came from peeling all those layers of wickedness and absurdity one by one, and it worked like a dream … as long as there were layers left. Once Laura Palmer’s killer was revealed midway through the second season, the final layer was gone, and the core turned out to be a mystical potluck of lodges, spheres, hirsute chaos spirits, and tiny, overdressed arm-deities.
