10 Most Insane TV Show Storylines Ever

6. The Lost Season Six Flashes

Avid watchers of ABC's Lost were treated to a whole lot of skipping about in time during the six season run of the show, with flashbacks taking up half the narrative of the first three seasons, and flashforwards beginning in season four (well, technically earlier, but that's another story). As if that wasn't confusing enough, actual time travel (as opposed to the story itself dancing backwards and forward it time) reared its ugly head in the story in season five, with half of the main cast having escaped the island, while the other half travel back in time on the island to the 1970s.

Season six, however, treated us to something entirely different: flashes sideways, apparently. The finale of season five saw the survivors, trapped in the past, attempt to detonate a hydrogen bomb on the island in order to prevent the original plane crash that began the series. It honestly makes much more sense when you've seen the show. Okay, maybe not much more.

With the cast returned to the present day once more and utterly flabbergasted as to a) why they were still on the island and b) why, if the bomb hadn't reset history, the blast hadn't just killed them (the audience was none the wiser), the now-traditional intercut flashbacks began showing viewers a different world of Lost - a world in which, it appeared, the plane crash actually had not occurred. Had the detonation of the bomb instead created an alternate timeline?

No, was the less than emphatic answer come the series finale. The apparent alternate timeline sideways flashes were in fact glimpses of a metaphysical afterlife that the protagonists had created in order to find each other after death, recall the most important time of their lives, and content, find the freedom to move on to whatever was next, one last example of Lost playing mind games with its audience before calling it a day.
