It feels like musical biopics are frequently produced as promotional tools for artists looking to capitalize on their past work; however, this film is notably different because of its raw and unfiltered approach, charting the journey of “Oasis” from humble beginnings—two brothers and friends practicing tirelessly in a basement—to worldwide fame. Both Noel and Liam Gallagher refrain from holding back when portraying not only their own complicated dynamic but also the exploitative nature of the music business and the considerable hypocrisy they encountered while striving for success and then dealing with its repercussions. The band, along with their manager Alan McGee, their loyal team members, and journalists who covered them at the time, provide a remarkably candid perspective—and the brothers seem unbothered by moments when they appear unlikeable, reckless, and immature. It's precisely this candor, combined with an impressive collection of archival footage and excellent audio quality, that lends the film a genuine feel, making it captivating to watch. The soundtrack is a potent reminder of the breadth of their musical output and the global scale of their popularity—despite their well-known misdeeds and destructive behavior. Furthermore, the movie explores how relationships within and beyond the band flourished and faltered over this brief but incredibly intense period, many of which are thoroughly recorded for our viewing, discomfort, and acknowledgment. The narration is delivered directly by those involved, through sound clips or contemporary interviews, reinforcing the sense that we're witnessing something authentic. Regardless of whether you appreciate them or not, it’s impossible to find this film dull.
