Among the Golden Globe Award nominees announced on Monday was a Latvian animated film that doesn't feature a single human character or word of dialogue. The National Board of Review and the New York Film Critics Circle have already named Flow the best animated feature of the year, over such heavy hitters as Inside Out 2 and The Wild Robot. Could this award season see the triumph of an underdog — or, to be more precise, an undercat? Catch Flow at the Savoy Theater in Montpelier. The deal A lean black cat examines itself in a pool of water. Nearby stands a house surrounded by monumental cat sculptures. Inside the house are a desk bearing an unfinished drawing and a bed where Cat still curls up to sleep. But whoever made the drawing and the sculptures is gone. Cat's world has changed before — witness the rowboat stranded high in a tree — and now it's changing again. A stampede of deer heralds a great wave that turns the forest to an ocean. Cat's house vanishes. Marooned amid rising waters, Cat makes a desperate choice to leap into a drifting sailboat that already holds an impervious capybara. Soon other animals join Cat and the capybara — a friendly golden retriever separated from its pack, an imperious secretary bird shunned by its flock and a ring-tailed lemur obsessed with a shiny hand mirror. Together they must figure out how to survive. Will you like it?

Cowriter-director Gints Zilbalodis offers a marginally gentler, PG-rated post-collapse scenario, in which animals menace but rarely eat each other on-screen. (An exception is made for the fish that fall prey to Cat — an obligate carnivore, after all.) The film offers all the elegiac beauty of exploring deserted cities with none of the nightmarish horror of, say, The Road. So yes, Flow could have been darker, but make no mistake — sensitive animal lovers of all ages will tear up. This isn't apocalypse lite. While the worst consequences of the disaster happen out of frame, we're given enough information to intuit them, and Cat's peril is palpable. If I'd seen…
