Not much can top Beyoncé's Emmy Award-winning Homecoming film in terms of concert documentaries, or Taylor Swift's Miss Americana. Demi Lovato’s Dancing with the Devil and Justin Bieber's Seasons make confessional attempts, but Pink's own diary of the run up to her Wembley Stadium gig explores another perspective - motherhood.

Pink: All I Know So Far, the new Amazon documentary on the prolific pop-punk singer Alecia Moore, emphasises the way in which the star balances her commitment to her children with the demands of her long-lasting career. The film is directed by Michael Gracey (The Greatest Showman), and acts as a love letter to the maverick, often misunderstood fans who’ve watched the musician grow up.

Having written letters to her children from pregnancy, the latest film is also a gift to Willow and Jameson. The eight-year-old and two-year-old might not remember all the details of their stage diva mother later on in life; but Pink: All I Know So Far will revive the madness of travelling the world and watching their mum sing upside down in mid-air above a stadium.

The fly-on-the-wall film was shot during three weeks of the Pennsylvanian's Beautiful Trauma World Tour, when she was traipsing through Europe (Dublin gets a shout out, and a Guinness Storehouse tour). Moore's husband of 15 years, former freestyle motocross champion Carey Hart, refreshingly supports her endeavours as a working mom. It's strangely poignant to see a pop icon relentlessly continue to tour after becoming a parent, which ultimately hinges on the support of a loyal partner.

The documentary points out that the former gymnast often simultaneously sings and performs acrobatics, two activities that pull in different directions. Her wire stunts on show at Wembley stadium, dozens of feet above the arena floor, are truly hair-raising - yet Gracey fails to dive into this excitement further.

Willow and Jameson inevitably become the main event throughout the clips, rather than Pink herself. Whether this will translate well with Pink-obsessed viewers remains to be seen, but the candid nature of the unapologetically real singer will always provide the foundations of a decent story.

However, Michael Gracey ultimately does little to challenge the singer, and barely scratches the surface of who she is as a person and how her career has evolved over the years. Fans who grew up with the star and are now parents themselves will thoroughly enjoy the touching portrayal of motherhood, but audiences from other categories may come away bored and disappointed at the lack of three-dimensional conflict. (But, as a 26-year-old childless non-gymnast non-performer, perhaps I'm just cold-hearted to the joys of babysitting? The jury's out on that one).

Pink: All I Know So Far is now streaming on Amazon Prime Video.
