Star Trek: 10 Horrific Episodes We Wish We Could Unsee

2. Deep Space Nine "Time's Orphan"

Chief O'Brien's 8-year-old daughter Molly is sucked into a timewarp. When she is recovered, ten years has passed for her. She's been living alone in god-knows-where and she's now a feral creature, barely better than a wild animal. The episode tried, I think, too hard to be original and ended up just being crappy, boring and incomprehensible. Probably the most unwatchable episode of DS9's entire seven-year run.
