At once fanciful and disquieting, “Tiny Big” presents a series of seemingly unrelated vignettes expressed through simple black-and-white line drawings, punctuated with occasional surprising bursts of color. Underscored by a soundtrack featuring the sounds of nature – wind, waves, crickets – the film eschews narrative, challenging viewers to draw their own conclusions about the significance of ritualized actions in a world that’s both hauntingly familiar and decidedly strange.
