Contrary to the headline displayed on this film’s poster, Disney’s The Beach Boys isn’t a definitive guide to the band. Instead, it plays like a “greatest hits” album that goes through their famous ups and downs. Their steady rise among American teens and leader Brian Wilson’s pop music innovations are covered, as are the more dour moments of their career, like the relentless abuse they got from their manager (the Wilsons’ father Murry) and the disagreements between Brian and his cousin and co-writer Mike Love. But for better or worse, the documentary doesn’t go into too much detail about these high-profile feuds, focusing instead on the joy and brilliance of their era-defining music, which tends to get buried beneath all the drama anyway. Because of this sunny approach, the film sometimes fails to match the band’s complexity. But there’s no denying that it’s just as enjoyable to watch as it is to listen to The Beach Boys’ music.
