Why read this explainer

Compare Eilis's daily adjustment with the more visible choice between Tony and Ireland. The warmer romance makes returning to Brooklyn affirming without removing the cost of having two homes.

PlotGeeks note

The warmer romance makes returning to Brooklyn affirming while the two-home structure retains its cost. Condensing everyday adjustment gives the final choice more visible control over the film's shape.
