For the first chunk of Last Christmas, self-proclaimed hot mess Kate (Emilia Clarke) is constantly dragging a big, battered suitcase along behind her. Flitting from the bed of a one night stand to a friend’s spare room and eventually, reluctantly, her family home, she literally carries her baggage around each day. The case ricochets over the London cobbles, following her heeled boots; a hardly subtle metaphor for the unpacked trauma that is weighing her down.
