As a virtuoso experiment, the freedom provided by animation maybe lets the camera “flow” a little too much. The film’s choice to integrate rather pretty 3D animation with more cartoonish designs produces mixed results for pure aesthetic pleasure, and in a brief 84-minute runtime it still manages to be a little repetitive.

Flow is a joy to experience but also a deeply affecting story, the work of a unique talent who deserves to be ranked among the world’s great animation artists.

The trouble with Flow is that it already looks dated — commendable to be sure, yet rudimentary at the same time. It’s as if Zilbalodis decided to dump an ocean’s worth of water in the Uncanny Valley. Still, animal-loving viewers will bond almost instantly with the cat and its motley companions.
