If you’ve been frantically sending letters to animation studios, begging them to make a kid-friendly CG-animated movie about the dangers of fracking and walruses, then “Arctic Dogs” is the extremely specific movie for you. Nobody else needs to buy a ticket, because although this film is hardly the worst of the year, it’s about as insubstantial as a tiny handful of snow.
Jeremy Renner lends his voice to Swifty, an anthropomorphic Arctic Fox who lives in the faraway, icy town of Taigasville. Arctic Foxes are bright white and disappear almost entirely into the snow, so nobody ever seems to notice him.
