The Greatest Season 1 (2026) Review – Jaalen Best’s Muhammad Ali Is a Knockout

Our Rating: ★★★★☆ 8.5/10

There has never been an authorised scripted series about Muhammad Ali — until now. The Greatest, Prime Video’s eight-episode limited series, arrives on 4 November 2026 with all eight episodes at once, and it earns its title in the way that matters most: not by worshipping its subject, but by showing how a boy from Louisville named Cassius Clay became the most famous man on the planet, and what that transformation cost him and everyone around him. Jaalen Best stars as Ali, in a breakthrough performance that carries the series, with Omari Hardwick and Dana Gourrier as his parents, Giovanni Ribisi as trainer Angelo Dundee, Amin Joseph as Sonny Liston and Michael Ealy as Malcolm X. Created by Ben Watkins and executive produced by Michael B. Jordan’s Outlier Society alongside Ali’s widow Lonnie Ali, it is the first scripted series made with the Ali estate’s blessing — and it feels like it.

This review is spoiler-free on the season’s dramatic specifics. Ali’s life is public history, but the series’ choices about which moments to stage, and how, are best discovered while watching.

Quick Facts: The Greatest at a Glance

The Story: From Cassius Clay to the Greatest (Spoiler-Free)

The season traces Ali’s formative years: from a young Olympic champion in Louisville to the heavyweight championship and the beginnings of his voice outside the ring. That arc is familiar from films and documentaries, but the series format gives it something no film has had room for — time. Eight episodes let the story breathe around the fights: the family home, where Cassius Clay Sr. (Hardwick) paints signs and dreams big while Odessa “Bird” Clay (Gourrier) holds the household together; the gym, where Angelo Dundee (Ribisi) teaches a loud young fighter to be a craftsman as well as a showman; the brotherhood with Rudy Clay (Kai Parham); and the collisions with the two figures who shaped Ali’s public conscience — Sonny Liston (Joseph), the fearsome champion he had to beat, and Malcolm X (Ealy), the leader who showed him that a voice could be a weapon too.

Watkins, best known for creating the crime drama Cross, structures the season as a coming-of-age story that happens to involve the heavyweight championship. The early episodes are the strongest: Louisville in the late 1950s and early 1960s is rendered with warmth and specificity, and the series is careful to show Ali as a son, a brother and a husband as well as a boxer — the private man behind the public poetry. The boxing itself is staged with real craft: the fights are not montages but character scenes, in which a jab or a taunt reveals who these men are. And the series never forgets that its subject’s greatness was controversial in its own time: the young Cassius Clay who announced himself to the world was loved and feared in equal measure, and the series lets both reactions live on screen.

Performances: Best Is the Discovery of the Year

Jaalen Best as Cassius Clay / Muhammad Ali — Best, previously seen in All American: Homecoming, carries the impossible role with astonishing confidence. He does not do an impersonation — no one could, and the series is wise not to ask — but he captures the rhythm of Ali: the speed of the feet, the speed of the mouth, the grin that was both a weapon and a shield, and the stillness underneath when the cameras were off. Early coverage ahead of the premiere pointed to a rare perfect Rotten Tomatoes score for the series, and Best’s performance is the reason most often cited. If the season has a single achievement, it is making you believe, for eight episodes, that this young man could become the most famous person alive.

Omari Hardwick and Dana Gourrier as the Clays — Hardwick is superb as Cassius Clay Sr., a sign painter and dreamer whose ambitions for his son are tangled with his own frustrations, and Gourrier is the season’s quiet heart as Odessa “Bird” Clay, whose faith and steadiness anchor a household hurtling toward fame. Their scenes together give the series its domestic gravity, and the family story is what separates this series from every Ali documentary.

Giovanni Ribisi, Amin Joseph, Michael Ealy and the ensemble — Ribisi is wry and precise as Dundee, the cornerman who understood that genius needs discipline; Joseph is a formidable Liston, all menace and melancholy; and Ealy’s Malcolm X is played with a seriousness that refuses caricature. Chris Jericho recurs as the flamboyant showman Gorgeous George, a reminder of where Ali learned that showmanship itself could be a strategy.

Direction and Technical Craft

Watkins directs the season’s opening episodes himself, with Stacey Muhammad and Craig Siebels also directing, and the craft is consistently strong: period Louisville feels lived-in rather than dressed-up, the gyms smell of sweat and leather, and the fight choreography favours clarity over flash — you can follow a round the way you could follow an argument. The series’ authorised status shows in its access to the family’s texture rather than in hagiography: Lonnie Ali’s involvement as executive producer has not produced a whitewash, and the season is frank about its subject’s youth, arrogance and mistakes.

The series’ one caveat is the familiar one of authorised biography: there are moments when the storytelling softens a hard edge, and viewers who know Ali’s later life — the seasons beyond this one, which the series does not cover — may feel the frame is deliberately narrow. The season covers the formative years only, ending before the chapters that made Ali a global political figure in full, and some will wish it had gone further. But as a first season of a life, it is remarkably complete: a boy becomes a champion becomes a voice, and the cost of each transformation is counted honestly.

Music and Sound

The music — jazz, soul and gospel textures woven through the Louisville scenes — gives the series its heartbeat, and the sound design in the fight scenes is superb: gloves on skin, canvas under feet, crowds that roar and then, in the series’ best moments, fall silent. The series understands that Ali’s story was always as much about sound — the poems, the predictions, the press conferences — as about punches, and it mixes both with care.

What Works and What Doesn’t

What we loved:

• Jaalen Best’s breakthrough, star-making performance as Ali
• The family story: Hardwick and Gourrier as the Clays give the series its heart
• Fight scenes staged as character scenes, not montages
• Eight episodes of room to breathe around a familiar life
• An authorised series that still allows its subject flaws and arrogance

What could be better:

• The authorised frame occasionally softens a hard edge
• The season covers only the formative years, ending before Ali’s later chapters
• Some viewers will want the political story pushed further
• The famous life means few plot surprises for those who know Ali’s story

Verdict: Should You Watch It?

Yes — and binge it. The Greatest is the rare biographical series that justifies its existence: not because Ali’s story was untold, but because it had never been told this way, with this much time, this much family, and a lead actor this good. It is the week’s essential streaming event, and the strongest new drama of the month.

Our rating: 8.5/10 — A knockout: Jaalen Best is magnificent, the family story is the heart, and Ali’s rise has never felt this human.
