10 Worst Rated Episodes Of All Time

Television has given us countless memorable moments, but even the best shows can stumble with episodes that leave viewers disappointed. From iconic series to fan favorites, some episodes stand out for all the wrong reasons, failing to capture the magic of their shows.

I’ve dug into the lowest-rated episodes across various series, focusing on those that sparked frustration or fell flat. Here are the 10 worst-rated TV episodes of all time, ranked from the least to the most disappointing, based on IMDb scores and viewer feedback.

House of Cards (2013-2018) – Chapter 73

The final episode of ‘House of Cards’ sees Claire Underwood, played by Robin Wright, trying to reshape her husband’s legacy after his exit. The absence of Kevin Spacey’s Frank Underwood left the show struggling to tie up its complex political threads.

I found this finale jarring, as it failed to deliver the sharp drama the series was known for. With an IMDb rating of 2.6, viewers called it a hollow end to a once-gripping show.

Riverdale (2017-2023) – Next to Normal

This ‘Riverdale’ musical episode, centered on Alice Smith’s mental health struggles, uses songs from the musical ‘Next to Normal.’ The shift to a Broadway-style format felt forced, clashing with the show’s usual teen drama vibe.

I was let down by the awkward singing and disjointed story, which didn’t blend well with the series’ tone. It scored a 3.2 on IMDb, making it the show’s lowest-rated episode.

Killing Eve (2018-2022) – The Hope That Kills You

The series finale of ‘Killing Eve’ follows Eve and Villanelle, portrayed by Sandra Oh and Jodie Comer, as they confront the mysterious Twelve. A shocking character death and rushed plot twists left the episode feeling like a betrayal of the show’s sharp writing.

I was frustrated by how it undid the chemistry that defined the series. With an IMDb rating of 3.3, fans found it a weak close to a thrilling show.

Star Trek: The Next Generation (1987-1994) – Shades of Gray

This ‘Star Trek: The Next Generation’ episode is a clip show where Riker, played by Jonathan Frakes, relives memories while injured. It was a budget-saving move, recycling old footage with minimal new content.

I found it dull and pointless, as it added nothing to the story or characters. Its 3.4 IMDb rating reflects its reputation as a low point for the series.

Riverdale (2017-2023) – Wicked Little Town

Another ‘Riverdale’ musical episode, this one uses ‘Hedwig and the Angry Inch’ songs as Betty and Jughead, played by Lili Reinhart and Cole Sprouse, navigate a chaotic school event. The singing and dancing felt amateurish, disrupting the show’s usual drama.

I cringed at the tonal mismatch and weak performances. Scoring 3.5 on IMDb, it’s another example of the show’s musical experiments falling flat.

American Horror Story (2011-2025) – The Future Perfect

The season 10 finale of ‘American Horror Story,’ part of the ‘Death Valley’ arc, tries to wrap up an alien-government conspiracy plot. The episode’s wild twists and rushed pacing failed to deliver a satisfying end to a shaky season.

I was confused by the messy storytelling and lack of closure. With a 3.7 IMDb rating, it’s seen as one of the show’s weakest entries.

Game of Thrones (2011-2019) – The Iron Throne

The ‘Game of Thrones’ finale sees Daenerys, played by Emilia Clarke, at the peak of her power before a shocking betrayal. The rushed pacing and character arcs, like Bran’s sudden rise to king, felt unearned to many viewers.

I was let down by how it fumbled the show’s epic buildup. Its 4.0 IMDb rating marks it as a divisive end to a cultural phenomenon.

Dexter (2006-2013) – Remember the Monsters?

The ‘Dexter’ finale follows Michael C. Hall’s Dexter Morgan as he faces the consequences of his double life. The episode’s odd choices, like Dexter’s final career shift, left key storylines unresolved.

I found the ending frustratingly vague, failing to honor the show’s intensity. With a 4.6 IMDb rating, it’s a sore spot for fans of the series.

How I Met Your Mother (2005-2014) – Last Forever: Part Two

The ‘How I Met Your Mother’ finale reveals the mother’s identity, played by Cristin Milioti, only to pivot to a controversial ending for Ted and Robin. After years of buildup, the rushed resolution and character deaths felt like a letdown.

I was annoyed by how it undermined the show’s core premise. Its 5.5 IMDb rating shows the widespread disappointment among viewers.

The Simpsons (1989-2025) – Lisa Goes Gaga

In this ‘Simpsons’ episode, Lady Gaga visits Springfield to cheer up Lisa, voiced by Yeardley Smith, after she faces bullying. The episode feels like a promotional stunt, with forced cameos and a lack of the show’s sharp humor.

I found it cringeworthy and out of touch with the series’ charm. With a 5.6 IMDb rating, it’s a low point in the show’s long run.
