16 TV main characters who ‘ruined’ the show

When TV characters ruin the show

Ever loved a series, only to find one character dragging the whole thing down? Sometimes it’s not the villains who ruin the fun, it’s the supposed heroes, sidekicks, or love interests who make viewers groan.

From annoying storylines to unbearable personalities, these characters shifted the vibe of beloved shows and left fans frustrated.

Scrappy-Doo (Scooby-Doo)

Introduced in 1979, Scrappy-Doo was meant to freshen up the Scooby-Doo franchise, but instead, he fractured its charm. Unlike the lovable cowardice of Scooby and Shaggy, Scrappy was loud, aggressive, and constantly ready to throw punches.

Fans of the original series felt his “puppy power” antics disrupted the mystery-solving vibe. His arrogance didn’t mesh with the gang’s laid-back chemistry, making many long-time viewers roll their eyes.

Piper Chapman (Orange Is the New Black)

Piper starts as the family-friendly lead in a gritty prison drama, only to reveal she’s self-absorbed to a fault. With fellow inmates like Taystee and Nicky offering layers of depth, Piper’s predictable moral tumbles and unearned self-pity felt insipid.

In many ways, her storyline became a roadblock to exploring richer tales around her. Eventually, the creators sidelined her, and the series found its rhythm only when Piper faded into the background.

Rachel Berry (Glee)

When a Broadway-dreaming teen becomes unbearable, the entire show starts to nosedive. Rachel Berry is wildly talented, but her compulsive neediness, self-centered diva behavior, and fragility made viewers cringe.

Instead of rooting for the underdog, audiences found themselves groaning at every high-note hissy fit. As much as you wanted her to succeed, her constant emotional manipulations overshadowed the ensemble’s diverse struggles.

Terri Schuester (Glee)

Will Schuester’s wife, Terri, turned from quirky spouse to serial credibility killer. Between her disastrous fake-pregnancy lie and relentless, shrill nagging, she quickly became the most detested person in McKinley.

Critics called her “the worst thing about Glee,” and her presence sucked energy out of every scene she occupied. It’s hard to cheer for a character who not only derails her husband’s dreams but drains the fun out of a joyous music show.

Dana Brody (Homeland)

A hitman’s daughter on the sidelines shouldn’t derail a high-stakes thriller, but Dana did just that. Her teenage angst and incessant whining threatened to derail Carrie and Brody’s powerful cat-and-mouse narrative.

Audiences widely agreed that she distracted from the show’s intensity, contributing little to the espionage drama and plenty to frustration. In a show about national security, teenage drama felt terminally off-sync.

Hannah Horvath (Girls)

Lena Dunham’s on-screen alter ego was meant to represent millennials, but instead felt emblematic of entitlement. Self-centered, melodramatic, and often obnoxious, Hannah’s behavior overshadowed her dark quirks.

Viewers hoping to see feminist grit ended up watching narcissistic drama. She weakened the ensemble’s chemistry, making the show feel like a showcase of vapid introspection, less relatable, more exhausting.

Emily Waltham (Friends)

Ross’s British bride should have been a breath of fresh air, but Emily became an obstacle to the show’s charm. Her possessive and unforgiving nature, especially during the iconic name slip incident, made her bitter rather than belt-worthy.

She pulled focus from the core characters, grinding the Ross-Rachel romance to a screeching halt. And for what? A temporary arc that left a sour taste.

Veronica (Breaking In)

Megan Mullally’s Veronica entered Breaking In with sass and turned the entire show off balance. Season 1 had a clever heist-comedy rhythm. Then Veronica swaggered in, hijacking tone with sarcastic one-ups and a glaring ego.

Fans recalled the shift: “The first season was great…and then Veronica happened.” She disrupted chemistry and diluted the quirky charm that made the original cast work.

Ted Mosby (How I Met Your Mother)

Ted’s painfully earnest storytelling started charming…until it didn’t. His incessant brooding over delivered punch lines and stalled romances slowed the show’s once-breezy momentum.

He epitomized the “broody guy syndrome”, overthinking every moment until the final episode dumped a heartbreaking blow. Many fans felt betrayed, saying the finale ruined nearly a decade of framing arcs.

Sam & Diane (Cheers)

Their electric tension fueled Cheers’ early seasons, but soon became toxic. Sam’s occasional threats and Diane’s self-indulgent snobbery pushed fun aside.

Critics pointed out their relationship was “completely unrealistic” and overshadowed the bar’s ensemble core. What began as romantic cleverness slipped into cringeworthy, and many breathed a sigh of relief when Diane left.

Barney & Robin (How I Met Your Mother)

The final season’s main storylines centered on Barney and Robin’s engagement, only for them to divorce three years later. Fans described the twist as a betrayal of character evolution.

Ted’s emotional journey, which hinged on believing in “the one,” unraveled in cheap shock, not narrative satisfaction. It was a finale that canceled the goodwill of nine prior seasons in one rushed ending.

Leonard (The Big Bang Theory)

The main character on The Big Bang Theory, Leonard Hofstadter, was the typical American nerd. Despite being anxious and sometimes picky, viewers kept liking him. People could relate to him easily because of his annoyance with Sheldon and his love for Penny.

Many people called to Leonard’s experiences in science and romantic remnants. Even though he was flawed as a hero, his concerns seemed genuine. The fact that he was smart and also awkward is what turned him into a well-known TV character, even if it bothered people at times.

Cosmo Kramer (Seinfeld)

Yes, Kramer is iconic, but as Seinfeld wore on, his eccentricity ballooned into full-on cartoonish chaos. What began as quirky neighbor energy evolved into outlandish, often mean-spirited stunts that strained believability.

Kramer’s behavior increasingly felt disconnected from any grounded humor. In earlier seasons, he added flavor; by the end, he often derailed scenes.

Some critics argue that while Jerry and George stayed semi-relatable, Kramer crossed into absurdity, testing the boundaries of what even a “show about nothing” could handle.

Emily Sanders (Emily’s Reasons Why Not)

Heather Graham’s titular character was Lucy-in-dangerous-waters boring. Critics and audiences panned her as a clichéd and dull lead so unlikable that ABC yanked the show after just one episode.

It proved that no star power can cure a lifeless, generic lead. When the lead leaves audiences cold, the show melts.

Hannah (Emily Archetype Recap)

From self-absorbed teens to toxic spouses, these problematic leads all have one thing in common: they believe their shallow introspection is enough to carry a story. But TV thrives on evolution, on characters who adapt, grow, or at least earn some empathy.

That’s where things get interesting, because sometimes, it’s the villain who steps up. When heroes fall flat, it’s often the antagonist who brings the tension, depth, or charisma that keeps viewers hooked.

Eric Forman (That ‘70s Show)

Eric on That ‘70s Show was both annoying and still a character we could relate to. Even though Eric was confused about many things, played by Topher Grace, he still wanted things done as he wished.

In the second series, ‘90s Show, grown-up Eric still had trouble with not being decisive and with giving in too easily. The troubled character of Randy made him both annoying and likable, given how the sitcom blended memories of the 1970s with humor from the 1990s.
