Mountain Queen: The Summits of Lhakpa Sherpa

Walker and her editors have created an absorbing narrative, so the film never feels as cobbled together as it actually is.

[Lhakpa's] resilience and sunny disposition light the film up, but it certainly shows a tough life, riven by conflicts, taking its toll.

This portrait of title subject Lhakpa Sherpa, the only woman to have summited Mount Everest 10 times, is so densely packed with uplifting moments that at times it feels like emotional mountaineering – but the climb has terrific views.
