Lost needed its worst episode in order to be saved. While it changed television forever and remains a beloved show more than two decades after premiering, a total of 121 episodes inevitably means that there are some weaker installments. Not all of them can live up to Lost's best episodes, including the season 3 finale, "Through the Looking Glass" and season 4, episode 5, "The Constant."

Season 3, episode 14, "Exposé" is often cited by fans as one of the worst episodes, with its focus on the season's newly introduced Oceanic 815 survivors Nikki Fernandez (Kiele Sanchez) and Paulo (Rodrigo Santoro) proving to be divisive. There are merits to the episode, and the ending is memorably haunting, but it brings the momentum of the story with Lost's Others to a grinding halt after several game-changing developments in season 3, episode 13, "The Man from Tallahassee."

For a long time, "The End" was widely considered to be one of the most controversial series finales of all time, but it has gained significantly further understanding and appreciation in more recent years. Its controversial status has also been usurped in popular culture by Game of Thrones season 8. On IMDb, the final Game of Thrones episode has a 4.0/10 rating compared to 8.4 for the first part of the Lost finale and an even more impressive 9.2 for the second half.

Lost's truly worst episode comes long before the sixth and final season anyway. It instead comes in the first half of season 3, both underlying an issue with the show's existing narrative structure and paving the way for a better future.

Season 3, Episode 9, "Stranger In A Strange Land," Is Lost's Worst Episode

Season 3, episode 9, "Stranger in a Strange Land" uses its flashbacks to tell the origin story behind the tattoos of Jack Shephard (Matthew Fox). The actor's real tattoos were featured throughout the show, but they did not require an episode dedicated to their backstory. The story that plays out feels forced, does not provide enough new insight into Jack to be warranted, and unintentionally reveals the limitations of including character-centric flashbacks in every episode.

In an interview with Esquire four years after the final season, co-showrunner Carlton Cuse was asked what he thought the worst episode of the series was, and answered that it was "Stranger in a Strange Land." He explained why he regrets the episode and how it exposed the bigger problem with always relying on flashbacks. Check out his comments below:

I mean, I think the episode where Jack gets his tattoos in Thailand. I think it's cringe-worthy, where he's flying the kite on the beach. It was not our finest hour. We used Matthew Fox's real tattoos. That's how desperate we were for flashback stories.

The present-day parts of the episode are not any better and do not prove to be very consequential. A new and seemingly powerful member of the Others described as "the sheriff" and named Isabel is introduced, but she never appears again after this. Kate Austen (Evangeline Lilly) and James "Sawyer" Ford (Josh Holloway) spend most of the episode bickering while Jack insists on being stubborn until he predictably relents and helps Juliet Burke (Elizabeth Mitchell). However, the lackluster installment ultimately had a major silver lining.

Lost Got A Definitive Ending Thanks To Its Worst Episode

In the same interview with Esquire, Cuse also explained that "Stranger in a Stranger Land" helped him and fellow showrunner Damon Lindelof realize that they needed to convince ABC to start gradually moving toward a definitive ending. The openness of the show's future led to forcing a flashback story with Jack that was completely unnecessary, and it was not something they wanted to repeat.

When we told the story of Jack flashing back to Thailand and how he got his tattoos, we really regretted that we had decided that was a worthy flashback story. That story became really instrumental in convincing ABC that we needed to end the show. We were like, "Okay, this is what flashbacks look like now so it's probably a good idea if we figure out how much longer this show is actually going to go."

While the series finale was divisive for years, even the biggest critics couldn't argue against the fact that the show had a definitive conclusion. From premature cancellations to other issues, this is something that many other shows do not get to have. Lost's ending didn't come until season 6, but many of the seeds for it were planted as season 3 continued, including the change in episodic structure.

The season 3 finale famously reveals that what appears to be Jack-centric flashbacks are actually flashforwards after he escapes the island and wants to go back. Thanks to the lows of "Stranger in a Strange Land" and moving toward an ending, the series was no longer beholden to flashbacks. In addition to the flashforwards, Lost's time travel and the flash sideways helped the story remain fresh and exciting in the remaining seasons, which Cuse confirms is part of what was intended.

The real exciting conversation happened in the middle of season three as we were begging ABC to end the show — the idea that the narrative device was going to flip out of flashbacks and into flashforwards.

Thanks to these positive changes and successfully building toward a proper ending, the frustrations that come with watching or revisiting "Stranger in a Strange Land" ultimately make the episode's existence a good thing, even though it is the worst in all of Lost.
