THIS IS US

Last episode ever! It’s the end of many eras as the back-flashing and flashforwarding family saga comes to a tearjerking close after six seasons. Recent episodes have found “The Big Three” — Pearson siblings Randall (Brown), Kevin (Hartley) and Kate (Metz) — coming together to care for their mother Rebecca (Moore) as she deals with Alzheimer’s after the death of second husband Miguel (Jon Huertas). Have the tissues ready — it’s going to get emotional as the Pearsons say goodbye in a surprising and satisfying finale.
