The film details the history of the Britpop band Oasis during their formative years and the height of their success in the 1990s, featuring off-screen interviews with members of the band, including Noel and Liam Gallagher, as well as people associated with them, set to archive video of concerts, contemporaneous interviews and backstage footage.

The website's critical consensus reads, "Oasis: Supersonic forgoes a comprehensive approach to its multi-platinum subjects in favor of an appreciative—and stirring—look at their heady early years.

"[9] On Metacritic, the film has a score of 71 out of 100, based on 16 critics, indicating "generally favorable reviews".

He summarised: "While Oasis: Supersonic is never boring, especially for fans, it's also not quite deep enough to justify its narrow focus, especially at its overlong running time.
