Kristen Bell and Ben Platt play siblings who don’t get along with their mother (Allison Janney). When their rich step-sister (Cynthia Addai-Robinson) invites them to England for her marriage, the dysfunctional delights begin. At least that’s what you’d hope, given the cast that’s so accomplished in comedy. In reality (or on screen), not so much. They’re romping thru the events leading up to the nuptials with energy, but the script lacks originality and there aren’t any memorable jokes. As a fluffy little escape, this works, but it’s destined to be quickly forgotten. (2 / 5)
