In a twist this week, Claire picks one of her favourite movies and a zombie flick that Lucy hasn't seen: the sensational Korean film Train to Busan. You want perfectly choreographed fight scenes? Check! You want hunky beefcake role models showing us nuanced interpretations of fatherhood? Bingo! You want a totally unsolicited musical number and thoughts on train safety? We got 'em! Plus Lucy sheds light on why this movie tears your heart right out (but not in the way you expect).
