Nailing an ending can be extremely challenging for any TV show. After all, these shows have long-running narratives that can be quite a pain to resolve, with fans being absolutely brutal when these endings don't wrap up all the plot threads in a nice and satisfying manner. This is perhaps why most people play it safe with their endings instead of trying to make things more artsy and open to interpretation.

That being said, there are shows with ambiguous endings that fans still adore. In fact, some of these shows enjoy a higher level of critical and commercial appraisal mainly due to how brilliant these endings can be, at times. While this might not be the case with the following shows on this list, these shows are still held in high regard and considered by many to be some of the greatest TV series of all time.

10 The Sopranos

The first TV show that comes to mind when talking about ambiguous endings is The Sopranos. After all, the show's final episode is notorious for having a confusing ending that felt almost like a broadcasting error.

However, this wasn't the case, with this blackout ending being completely intentional. The fact that this ending has become one of the most legendary conclusions in television history is a testament to just how beloved The Sopranos is.

9 Dexter

Regardless of what most people think about Dexter, there's no denying the fact that the series was the best and most riveting show during its heyday. Unfortunately, the last few seasons missed the mark royally, with Dexter's ending being particularly revolting.

This time, the ambiguous nature of the ending wasn't well-received by fans. A lot of plot points were left up in the air, with Dexter's future being a source of mystery. Thankfully, Dexter: New Blood has revitalized the series and given some much-needed context when it came to the serial killer's current situation.

8 Hannibal

It's a shame that Hannibal didn't get more breathing room to conclude its riveting story. As it stands, the show received a meager three seasons that simply weren't enough to cover the incredible story.

The final season of Hannibal especially suffers as a result of this rushed storytelling. The finale could've been a thing of beauty — and it is, at times — but the obtuse nature of this conclusion was more frustrating than enlightening for many.

7 Mad Men

Jon Hamm in Mad Men

Mad Men is a brilliant drama that takes a look at America and the advertising industry during the 1960s. The characters and overarching plot threads are absolutely brilliant, making for one of the greatest TV shows of all time.

Don Draper is a brilliant character whose personal arc takes a drastic turn near the end of the series. In the final moments of the series, it genuinely seems like Don has achieved his inner peace... although his future is still very much up in the air.

6 Lost

Lost

Lost was a phenomenon back when the series had creativity oozing out of every pore. However, after a while, the show lost the plot — ironically enough — and turned into a shell of a great show.

This was especially evident in the ending, which dropped most of its riveting plot threads for a lazy cop-out that made everyone's investment in this show completely worthless. Perhaps things could've been better for Lost had it condensed the plot to a few seasons and removed most of the pointless filler content.

5 Game Of Thrones

Game of Thrones Brienne and Jaime

Game of Thrones is another example of a great show that ultimately lost everything that made it iconic and became a chore to watch near the end. The quality of this show dipped so immensely that the franchise lost its footing in pop culture and has simply become a remnant of the past.

Fantasy series like The Lord of the Rings and Harry Potter became legendary mainly because their quality was constant throughout the experience. However, Game of Thrones was such a massive disappointment that this rich and diverse world is barely talked about now, mainly due to a horrible ending that resolved nothing and came out of nowhere.

4 Seinfeld

The greatest sitcom of all time had some excellent writing that made it such a cultural phenomenon. To this day, Seinfeld's characters and tropes still hold a soft spot in the hearts of many fans.

The final episode of the show was a scathing look at the heinous acts of the main cast, leading to them being hauled off to jail. While this would've marked a dark chapter in the lives of these characters, Seinfeld brushes off this notion with some classic jokes before fading away and leaving the fate of the characters up in the air.

3 Squid Game

Netflix has slowly greenlit its fair share of engaging Korean dramas and the like, but it's hard to believe that this streaming giant could've expected the massive popularity of Squid Game. This brutal Korean show takes an uncomfortable look at the evils of classism and how the rich constantly torment the poor every step of the way.

Squid Game is not a show for the faint of heart, with its ending making it clear that Seong Gi-hun wasn't finished with the elite organization behind the evil actions of this killing game. Most Korean dramas don't really feature multiple seasons, and Squid Game is apparently going to end on this sinister note unless a second season is officially announced.

2 Sherlock

There was a time when Sherlock was revered by the masses as one of the greatest television shows of all time. Unfortunately, the latter half of this show failed to live up to the extremely high standards set by its first two seasons.

That being said, Sherlock is still a great show that fans should definitely watch all the way to the very end. However, since there's been no word on a Season 5 for the longest time, it seems that this show is bound to end on a rather ambiguous and unsatisfactory note.

1 Fargo

Fargo

Each season of Fargo deals with a different narrative and completely new characters. Given the artistic and complex nature of this narrative, almost all seasons end on thought-provoking and open-ended notes.

What makes Fargo such a massive achievement is that none of these ambiguous endings take away from the overall quality of the show. Even its weakest season is miles ahead of most modern TV shows.
