A surprising film debuted at Sundance 2024, and you could say it’s got buzz. And whistles, beeps and chirps. Sally Aitken’s documentary Every Little Thing (B) is a gentle, non-ironic glimpse at the life’s work  of a West coast woman named Terry Masear, who operates a hummingbird rescue mission out of her L.A. home. This consummate and patient healer’s own wounded background undergirds the true tale, but the recovering birds are really center cage in this realm, each with cute names and back stories as they begin their fragile resurgence. Aitken gently follows some amazing animals in startling close-up as they learn their flights of fancy again. Like March of the Penguins, it’s a canny diorama exploring the sociological machinations of a bird order. This engaging journey is quietly observant, inspiring and entertaining.
