10 Most Insane TV Show Storylines Ever

5. The Entire Final Season Of Fringe

Always the crazy mad scientist cousin to The X-Files - conspiracy-obsessed lone gunman (and there are plenty of theories that suggest that Fringe actually takes place in the same universe as The X-Files, making it a successor in more ways than one), Fringe actually one-upped itself come the abbreviated final season. Well, it was a J.J. Abrams show.

Already dealing on a daily basis with the kind of strange phenomena that would make up the oddest X-Files episodes, the protagonists had, throughout the first four seasons, been visited by strange men, Observers, with alien physiologies and mindsets. Even the episodes which didn't feature Observers would have one of the bald, albino men in suits somewhere in the background.

At the end of season four, we were suddenly yanked into the future, where in 2035 the Observers had subjugated the human race, revealing themselves to be the human race from the 27th century. The entire rest of the show would be a dystopian post-apocalyptic guerilla war to restore history. Utterly bananas.
