This high-energy look at the highs and lows of breaking up and making up by first-timer Sam Esmail alternates between original and overwritten, simplicity and convolution, elegance and fussiness.

The timeframe-jumping structure can be distracting, but it somehow fits in with how one might look back over incidents in the lifespan of a relationship.

Worth a look, depending on your resistance to talky movies. I’ve sat through much worse. (91 min)
