Blue Jay doesn’t lean on destiny or succumb to the easy refrain that time is a great equalizer. There’s genuine happiness here, but heartbreak is always right behind it.

The script is loose; the acting is natural and nuanced. Over the credits plays an acoustic song about lives in the how-did-we-get-here stage. If you do not leave this Netflix movie asking questions about your own paths, the failing is yours, not Duplass’s.

Mark Duplass and Sarah Paulson have extraordinary chemistry, painting a cumulative portrait of the fragility and rareness of being truly in sync with a partner.

Duplass and Paulson counteract the deliberately banal dialogue (Duplass also wrote the screenplay) with superbly anxious body language; Jim and Amanda’s “casual,” “amiable” chitchat is so painfully forced that it’s a wonder nothing ruptures.

Luckily, Blue Jay boasts a handful of fresh, piercingly poignant scenes that cut through the cloud of déjà vu. It also has a not-so-secret weapon in the formidable Paulson, who deserves much of the credit for whatever emotional punch the film delivers.
