As of October 7, 2026, five seasons in Rotten Tomatoes’ current Certified Fresh guide show a perfect 100% Tomatometer score: Slow Horses season 6, Adults season 2, Mel Brooks: The 99 Year Old Man! season 1, Colin from Accounts season 3, and President Curtis season 1. These are perfect critics’ scores for individual seasons—not a claim that every season of each series earned 100%.
What a 100% Rotten Tomatoes score means
The Tomatometer is Rotten Tomatoes’ critics’ score: the percentage of counted critic reviews that are positive. A 100% score means every review counted for that season is positive; it does not mean that every critic assigned a perfect numerical rating. Rotten Tomatoes also displays its separate Popcornmeter, an audience score, and those percentages are not always the same. Scores can change as reviews are added.
The following entries are the five seasons shown at 100% in Rotten Tomatoes’ Certified Fresh guide, published September 23, 2026, as captured on October 7, 2026. Check the current guide for updated scores.

Slow Horses, season 6
The sixth season of Apple TV’s spy drama has a 100% Tomatometer and a 91% Popcornmeter in the guide. The series is based on Mick Herron’s Slough House novels. Apple announced that season 6 would premiere September 16, 2026, and said its first five seasons were streaming on Apple TV in that announcement. Apple’s announcement has the premiere and availability details; check the service for current access. If the show’s world appeals, Herron’s novel Slow Horses is a companion read rather than part of a streaming subscription. Hachette’s Mick Herron page identifies the novel as the book behind the Apple TV series.
Adults, season 2
The second season of Adults pairs a 100% critics’ score with a 97% audience score in the guide. That small gap makes it the closest critic-audience match among these five listings.

Mel Brooks: The 99 Year Old Man!, season 1
This documentary season has a 100% Tomatometer and 96% Popcornmeter. Rotten Tomatoes’ editorial consensus characterizes it as an affectionate, humorous retrospective while noting the heartbreak in Mel Brooks’ life. The strong comedy-documentary framing should not be mistaken for a claim that the film avoids more difficult parts of its subject’s story.
Colin from Accounts, season 3
The third season of this romantic comedy is listed at 100% with a 96% Popcornmeter. Rotten Tomatoes describes the series in its consensus as an unconventional, empathetic romantic comedy.
Rank #3
President Curtis, season 1
The first season of this animated Rick and Morty spin-off has a 100% Tomatometer but a 75% Popcornmeter—the widest gap in this group. Rotten Tomatoes’ consensus describes its meta humor as landing with critics. That difference is a useful reminder that a perfect critics’ score does not imply equally strong audience approval.

Rotten Tomatoes scores individual seasons as well as series, and the five 100% entries in the 2026 guide are all seasons. A viewer looking for a particular show should therefore check the season named, rather than assume that earlier or later installments share its score. Rotten Tomatoes also has a separate guide to TV seasons with 100% Tomatometer scores; its November 3, 2025 update says it collects perfect-score seasons and ranks them by review count. That separate guide is not the basis for treating this 2026 list’s order as an all-time ranking. Read Rotten Tomatoes’ separate perfect-season guide.
