8 Great TV Shows Turned Into Terrible Movies

Picking the greatest TV shows ever made is tough because there’s so much variety, but many of the most memorable ones actually end up influencing our culture – creating famous lines and characters that are as popular as those in big movies. Traditionally, TV was seen as secondary to film, but now, with streaming, successful franchises often expand into movies and short-form content. While it makes sense to think a fantastic TV series would also work well as a movie, that isn’t always true.

Successful movie adaptations of TV shows manage to stay true to what made the original series special, while also offering something new that justifies a longer movie length. Sometimes this means expanding on a story too big for a single episode, as seen in South Park: Bigger, Longer, and Uncut. Other times, it’s about providing closure, like Serenity, which gave fans of the canceled show Firefly a satisfying ending. However, just because a TV show is great doesn’t automatically mean its movie adaptation will be – some truly excellent series have been tarnished by surprisingly bad films that end up defining the franchise instead.

The Avengers

The 1960s TV show The Avengers was a standout of its time and remains enjoyable today thanks to its witty British humor and memorable style. Though many now associate The Avengers with the Marvel superhero films, the original series was a completely separate entity – and a highly acclaimed spy show, earning a 91% positive rating on Rotten Tomatoes. Sadly, the 1998 movie adaptation didn’t fare so well.

Despite starring Sean Connery and Uma Thurman, the movie was a critical and audience failure, scoring only 5% on Rotten Tomatoes from critics and 15% from viewers. It didn’t capture the unique charm of the original series and made the unpopular decision to create a romantic relationship between characters John Steed and Emma Peel, whose connection had always been intentionally left open to interpretation. Like many poorly received films, the reviews were more enjoyable to read – Jeremiah Chechik of The Radio Times called it “misguided and misbegotten to a simply staggering degree.”

Lost In Space

Lost in Space is a sci-fi take on the classic story of Swiss Family Robinson. It follows the Robinson family, who are part of a group of colonists that crash-lands on a strange planet and must learn to survive. The original 1960s TV series is a fun, adventurous show that remains enjoyable even today. However, the 1998 movie adaptation hasn’t aged as well and primarily aimed to update the show’s special effects.

Gary Oldman is usually great at playing villains, but even his performance couldn’t rescue this movie, which critic Roger Ebert famously panned, comparing it to something that would be indistinguishable if lost in a black hole. It’s particularly disappointing because the original TV show was clever and resourceful, with the family constantly finding new uses for the ship’s parts. A movie focused on that ingenuity – with less emphasis on action and more of the show’s lighthearted spirit – probably would have been much more successful.

Entourage

Revisiting Entourage reveals that the show hasn’t held up over time, even though it still enjoys a fairly positive audience score of 82% on Rotten Tomatoes (critics give it a 66% rating). Like classics such as Sunset Boulevard, the series originally aimed to satirize Hollywood. Unfortunately, the Entourage movie itself wasn’t successful with either critics or audiences.

The Entourage movie brought back most of the original TV show’s actors and continued the story, but it surprisingly altered some character developments. For example, Ari, who had stepped away from his demanding career to focus on family in the series finale, was back in business as if nothing had changed. While the film featured many celebrity appearances, it didn’t offer much in the way of fresh ideas. Critics also pointed out the movie’s portrayal of women, which felt particularly inappropriate considering past allegations against some of the guest stars, such as Sean Combs.

Avatar: The Last Airbender

Avatar: The Last Airbender is one of the few truly great TV shows that appeals to everyone, from kids to adults. It tackles complex themes like war, prejudice, and forgiveness, and cleverly draws inspiration from different Asian cultures in its depiction of the various nations. The movie adaptation directed by M. Night Shyamalan was quickly criticized because it didn’t respect these cultural roots, primarily casting white actors instead, and even casting Indian actors to play the villains.

Avatar: The Last Airbender TV show vs. movie
Title	Format	Year	Rotten Tomatoes critics’ score	Rotten Tomatoes audience score
Avatar: The Last Airbender	TV series	2005	100%	98%
The Last Airbender	Movie	2010	5%	30%

The problems with the Last Airbender movie went beyond just its overall failure. The film didn’t capture the core idea of “bending” as it was presented in the original animated series. The TV show excelled at world-building, depicting bending as a unique martial art style for each element. The movie, however, simplified bending to just a dance, and lost the playful, lighthearted tone of the series, which was important because the characters were all kids.

The Wild Wild West

Among classic Western TV shows that truly made an impact, The Wild Wild West stands out as particularly thrilling. It arrived as traditional Westerns were losing popularity and spy shows were gaining traction, cleverly combining the two with elements of science fiction. This unique blend of Victorian aesthetics and futuristic technology essentially created the steampunk genre, and it’s a style that’s instantly familiar today.

Okay, so I recently revisited Will Smith’s Wild Wild West from 1999, and visually, it’s actually pretty impressive – especially that giant mechanical spider! But honestly, that’s where the good stuff kind of stops. Critics really weren’t fans, and it only scored a 16% on Rotten Tomatoes. The biggest problems were the story, the characters felt flat, and the whole movie just felt like it prioritized looking cool over actually being good, from beginning to end.

The Flintstones

Everyone knows The Flintstones, even if they haven’t watched the show – most people recognize the theme song and characters. With its unique style and premise of a “modern Stone Age family,” it was inevitable that it would be adapted into a movie. Back in the 1990s, animated films weren’t taken as seriously as live-action movies, so the filmmakers decided to bring The Flintstones to life with real actors.

The colorful characters from the TV show didn’t quite work on the big screen. Although John Goodman gave a strong performance, the movie hasn’t held up well over time and wasn’t a hit with audiences when it was first released. The story, which included themes like stealing money, was also an unusual choice for a children’s film. While Halle Berry’s character was progressive for its time, it lacked depth, and the movie only received a 23% approval rating on Rotten Tomatoes.

Sex And The City

While Sex and the City doesn’t hold up as well today, it was incredibly innovative when it first aired in the 1990s. Many viewers connected deeply with the show by seeing themselves in one of the four main characters. It became a major cultural moment and is still analyzed by scholars, though its reputation has suffered due to the quality of the two sequel movies where the original cast returned.

Okay, let’s talk about the Sex and the City movies. The first one did pretty well at the box office, even if critics weren’t exactly raving about it. But the second film? Yikes. It really bombed with both reviewers and audiences. I mean, a 16% rating on Rotten Tomatoes from critics and only 43% from viewers? That’s rough, especially considering how much people loved the original series. And honestly, it wasn’t just the poor reception – a lot of people found the movie to be genuinely problematic in how it depicted women, LGBTQ+ individuals, and cultures in the Middle East. It just didn’t land well, and for a lot of good reasons.

The Lone Ranger

The Lone Ranger is a hugely recognizable figure in Western television, representing the ideal cowboy hero. Though several films have been made about him, some parts of the story haven’t held up over time, particularly the portrayal of Tonto, his Native American companion who is often the true hero. A new movie could have updated the series and launched a fresh start, but the unsuccessful film directed by Gore Verbinski effectively ended any chances of that happening.

Disney’s The Lone Ranger wasn’t successful, despite having a strong start with the team behind Pirates of the Caribbean – including the writers, director Gore Verbinski, and star Johnny Depp. However, the film faced criticism, particularly for casting Depp as Tonto, a role many felt should have gone to a Native American actor. The story also felt weak, and at nearly two and a half hours long, the movie was simply too drawn out.
