This is a highly respected Russian film (Original title: Петровы в гриппе) that competed at Cannes. It is rated a solid 79 at Metacritic.
A day in the life of a comic book artist and his family in post-Soviet Russia. While suffering from the flu, Petrov is carried by his friend Igor on a long walk, drifting in and out of fantasy and reality.
Variety wrote:
Through its heady stew of impulses and influences, Petrov’s Flu is cinema to the breathless last, riding the camera like a bucking horse as single shots carry us between locations, eras and states of mind — the thrilling, messy work of a man released.
