At times almost too unbearably intense to watch but ultimately rewarding and with an uplifting twist, “Infinite Storm” is based on the amazing, true-life story of one Pam Bales, who in 2010 set out on an excursion to the top of Mount Washington, the highest peak in the Northeastern United States, which is famous for its unpredictable weather and exhilarating but dangerous paths.

Enhanced by an all-in performance from Watts and impressive behind-the-camera work, Infinite Storm is a ride that's both engrossing and emotional.

This is a daring and memorable depiction of trauma, compassion and resilience.

With this role, Watts is reminding us that she can hold the screen by herself and without saying a word tell you everything you need to know about a character — and all the while looking fantastic.

Watts’ stoic, sturdy performance and the film’s affecting and formula-busting third act make this Infinite Storm well worth weathering.
