“A Star Is Born” might have been a better title for the final chapter of Steve McQueen’s Small Axe anthology, not least because it opens with 12-year-old Kingsley (newcomer Kenyah Sandy) watching the start of the universe in a planetarium, but because it chronicles the turning point in McQueen’s own journey to genius – a heartfelt, deeply personal coming-of-age story about his own childhood struggles. “A nuclear heart is beginning to beat”, announces the show in a line loaded with meaning, as Kingsley gazes up and dreams of one day being an astronaut. McQueen’s own passion first ignited in the late 70s where he grew up in West London and found a love of art and film – but not before he was almost crushed by a racist, broken school system that overlooked his dyslexia and segregated him from the rest of his class.
