Prime Video’s biographical series “The Greatest” focuses on Muhammad Ali’s early career, tracking Cassius Clay from Olympic gold to his first heavyweight-title opportunity. Across coverage, outlets describe an eight-episode season that covers the period leading up to Clay’s fight with Sonny Liston, with the show presented as both dramatic and character-driven.

The series is created by Ben Watkins, and multiple outlets highlight the performances around the role of Ali/Cassius Clay—particularly actor Jaalen Best. Newsweek emphasizes the “human side” of portraying Ali and the pressure involved in that task, while the Hollywood Reporter frames Best’s performance as star-making. The Los Angeles Times focuses on how the show depicts Clay’s evolution into Muhammad Ali, also noting Ali’s widow’s involvement among the show’s executive producers.

Overall, the outlets largely agree on the show’s scope and key storyline beats, with differences mainly in emphasis—performance versus character pressure versus narrative evolution—rather than on disputed content details.
