Best Series of All Time: Highest-Rated & Must-Watch Shows

Few debates in pop culture are as persistent as the one over the best series of all time. Audiences and critics often see the same shows through different lenses, producing rankings that can look almost unrelated.

IMDb Top 250 number one series: Breaking Bad (9.5) ·
Rotten Tomatoes fan pick top series: Breaking Bad ·
Highest rated series on IMDb (2025): Breaking Bad – 9.5 ·
Most watched US scripted episode: M*A*S*H finale (106 million viewers)

Here are key facts about the best series.

What is the top 10 best series of all time?

How are top 10 best series lists compiled?

Most top 10 lists rely on either aggregated audience ratings (like IMDb) or critic scores (like Metacritic). IMDb’s list is built from millions of user votes, making it a crowd-sourced snapshot of popularity and rewatch value. Metacritic’s browse page collects professional critic reviews, emphasizing innovation and cultural impact. The two methods often produce very different lineups.

Which series appear most frequently in top 10 lists?

• Breaking Bad nearly always appears near the top of audience-driven lists, holding a 9.5 IMDb rating (IMDb audience ratings).
• The Sopranos and The Wire are staples of critic-based and audience lists alike (IMDb audience lists).
• Game of Thrones features prominently in global viewership rankings, though its final season tempered critical consensus.

The pattern: lists from IMDb and Metacritic rarely align, and the divergence grows as you compare deeper rankings.

What are the 10 most watched series?

How are viewership numbers measured?

Nielsen ratings remain the standard for US television audiences, tracking live and delayed viewing. Streaming platforms report their own proprietary data, making cross-platform comparisons tricky. The M*A*S*H finale in 1983 drew 106 million viewers, a record that still stands for scripted US television (Nielsen data).

What is the most watched single episode of a series?

• Game of Thrones series finale (2019) – 13.6 million live+same-day US viewers (Nielsen).
• The Walking Dead season 5 premiere (2014) – 17.3 million (Nielsen).

What this means: viewership numbers capture a moment in time, not necessarily quality.

What is the No. 1 series of all time?

What are the big 3 TV shows?

In audience polls, Breaking Bad routinely claims the No. 1 spot with a 9.5 IMDb score (IMDb audience ratings). Critics often champion The Sopranos or The Wire as the pinnacle of television storytelling (Metacritic critic aggregate). Documentary series like Planet Earth II also tie Breaking Bad on IMDb, proving that non-fiction can compete with drama.

One pattern: the “big three” in most discussions are Breaking Bad, The Sopranos, and The Wire. Each represents a different peak—intense character arc, anti‑hero revolution, and systemic realism respectively.

Four series, one pattern: the gap between user ratings and critic scores reveals how different metrics pick different winners.

The catch: the method you choose—audience or critic—determines which show wins.

In short, no single answer satisfies every viewer’s priority.

What is the highest rated series?

Which rating platforms are most authoritative?

IMDb (user voting) and Metacritic (critic aggregation) are the two most referenced sources. Rotten Tomatoes offers a split between audience and critic scores. For the highest single rating, Breaking Bad and Planet Earth II share an IMDb score of 9.5 (IMDb audience ratings). Among critics, Band of Brothers holds a 97% on Rotten Tomatoes and O.J.: Made in America tops Metacritic’s TV list (Metacritic critic aggregate).

How do audience scores differ from critical scores?

• Audience scores often reward rewatchability and emotional impact (Breaking Bad).
• Critical scores prioritize innovation, writing, and cultural influence (The Wire, The Sopranos).
• Documentary and limited series score higher on critic aggregates than in audience polls (Metacritic top TV browse).

The pattern: audience and critic lists diverge most for non-fiction and niche comedies.

What series should everyone watch once?

What makes a series a must-watch?

Must-watch lists blend cultural significance, storytelling excellence, and broad appeal. The Wire, Breaking Bad, and Band of Brothers appear on nearly every such list. Avatar: The Last Airbender is a frequent recommendation for animation fans, praised for its world‑building and character arcs.

Which series are universally recommended?

• Breaking Bad – for its tight plotting and character transformation.
• The Wire – for its unflinching look at institutions.
• Band of Brothers – for its immersive war storytelling.
• Chernobyl – for its tension and historical weight.
• Planet Earth II – for its visual wonder (Metacritic critic aggregate).

What this means: the best series for you is the one that aligns with your taste, not a consensus pick.

“Breaking Bad is widely regarded as one of the greatest television series of all time.”

Wikipedia (reference encyclopedia)

“The Wire is frequently defended by critics and fans as one of the greatest television dramas ever made.”

IMDb audience list commentary

“The Office (UK) is ranked very highly by Metacritic, indicating strong critic approval for British comedy series.”

Metacritic (critic aggregate)

For anyone trying to settle the “best series of all time” argument, the real answer is a trade‑off. If you value audience passion, Breaking Bad is your winner. If you prioritise critical rigor, The Wire or The Sopranos take the crown. The choice is yours—but the shows that top both lists are the ones that truly deserve your time.
