Kate Winslet as Mare Sheehan, “Mare of Easttown” 

HBO, 2021

It comes as little surprise that, since Mare took steps toward forgiving herself in the final episode of “Mare of Easttown,” fans have been anticipating a Season 2. Mare, consumed by roiling emotion that she hid behind a tough attitude and draws on her vape, felt so rounded, complex and real that it seems painful to leave her behind for good. A has-been high school athlete whose life since graduation had been a mix of a few ups and a lot of downs, Mare forced herself through each day on her police-detective beat, until the possibility of solving a complex and knotty case — and the new friendship of a county cop (Evan Peters) — brought her to life. “Mare of Easttown” was a portrait of grief that somehow never quite felt heavy, in part because Winslet lent Mare a let’s-get-through-this gumption. You believed that she was in pain; you also, somehow, believed that she would be OK.
