If you loved A Serious Man, try To Each His Own Cinema
A bridge between a film you've already seen and one most people haven't. To Each His Own Cinema has roughly 15.4× fewer votes than A Serious Man — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Ethan Coen, Joel Coen, and they both carry the cerebral mood tag, and they sit in Comedy / Drama territory. If that's the register that drew you to A Serious Man, the second film will land in a comparable space — through a different lens.
What To Each His Own Cinema is
A collection of shorts, then, each director offering what amounts to a cinematic shrug. Thirty-three filmmakers respond to the prompt of what cinema means to them. The result is a mixed bag, though at least it's reliably brief.
