Keira Knightly hosts a literal end-of-the-world Christmas party for her well-to-do family and friends. The festivities occur with the looming threat that they are all about to pop a suicide pill before the deadly poison reaches their country mansion. I found this to be a clear commentary on the suicidal nature of Brexit -- showing the stupidity of those who are voting against their own best interests. The film has some amusing moments and decent performances, but ultimately peters out to a gimmicky insignificance.
