It's easy to get sucked into your favorite television series and loyally watch every episode. But ultimately, all good things must come to an end, and every TV series ultimately has to reach a conclusion. Whether or not that conclusion is satisfying is an entirely different story.

Some finales leave audiences with smiles on their faces, feeling like they got to bid a proper farewell to their beloved show, but others leave fans sitting there wondering what just happened. When it comes to the most disappointing series finales, these Redditors felt that these were the series that belong on that list.

When How I Met Your Mother first premiered in 2005, fans fell in love with the comedy. The series follows five friends living in New York City, and one of them, Ted, seems to be on a quest to find the future love of his life.

For nine seasons, fans stuck with the show and followed Ted's disastrous love life, all waiting for the moment he met the mother. But the disappointment was palpable when the series ended, with the mother dead and Ted going back to his ex. Redditor KneeHighMischief said, "How I Met Your Mother is the gold standard for bad finales. I can't believe they had all those years to get it right only to fail so spectacularly."

9 'Smallville' (2001-2011)

The hit CW series, Smallville, ran for 10 seasons in the early 2000s and told the story of Superman before he was Superman, following his adolescence. The series gave audiences an interesting dynamic between Lex Luthor and Clark Kent and one of the best iterations of Lois Lane on screen.

While there was a lot to love about Smallville, some fans felt the finale did not give them what they had eagerly been waiting to see, which was Clark Kent becoming a fully realized superhero and feeling let down that they never got it. Reddit user Bruinsrock11 writes, "Smallville where we waited 10 years for Tom Welling to don the Superman suit instead it was CGI on him and shown for 30 seconds."

8 'Dexter' (2006-2013)

Dexter, the crime drama series, follows the life of a serial killer. The protagonist, Dexter, played by Michael C. Hall, leads a double life as both a man who desires to kill and a man who does forensics for the police homicide department.

Audiences generally loved the show but became concerned with some plots in the final season. Just when fans thought it was all coming together, the finale aired, and hearts were broken. As Redditor BoostJunkie42 puts it, "Nothing will EVER top Dexter for me when it comes to the biggest letdown."

7 'Chuck' (2007-2012)

While the show was largely considered a fun and dynamic crime-fighting saga, the ending left fans with questions and feeling the characters weren't used as well as they should have been. Reddit user Fallcious said, "I rewatched through to the last season and disliked the general direction. Then I remembered how the series ended and decided to quit mid-way instead."

The fantasy series that became a pop culture icon, Game of Thrones, garnered a strong fan base. The story follows several noble families as they battle to gain control of the mythical land of Westeros while also facing numerous other threats and challenges.

Despite the huge acclaim the show received from both critics and fans alike, audiences were less than pleased with the show's final season and the ending they were given. Reddit user tinoynk explains, "That whole final season was so rushed...These intricately arranged stories get so abruptly wrapped up in quick succession. So disappointing."

When it comes to the Star Trek franchise, there is no shortage of various ship crews to follow and adventures to take part in, some more successful than others. Star Trek: Enterprise takes place 100 years before the existence of renowned Captain James T. Kirk and explores the history of the first Starship Enterprise.

Trekkies have been torn about where this series ranks compared to others in the franchise, but many don't rank it highly. Nevertheless, for the loyal fans who stuck by it, they felt completely betrayed by the series finale and the death of a beloved character. Redditor meatball77 said, "The Enterprise finale was so bad that people pretend it didn't exist."

The series followed the story of the dynamic duo of two brothers, Sam and Dean, as they followed in their father's footsteps to battle monsters, demons, and any other beings that didn't belong in this realm.

After fans had invested 15 years into the series, there were big expectations going into the final season and concluding episode. So much had gone into these stories, but some felt the ending didn't measure up. Redditor vilandra21 writes, "...years of development were thrown out the window you could pretty much watch the pilot and finale and be fine."

So no one told you life, or the finale, was going to be this way. When it came to the finale, some fans felt that the Ross and Rachel storyline should not have ended the way it did and should have gone their separate ways. Redditor Infamous-Lab-8136 says, "I would've prefer Rachel told Ross to get stuffed, she's taking the job on Friends. Them together quit being my idea of a happy ending for the show around season 5 or 6."

1 'Ozark' (2017-2022)
