If you could go back in time whenever you liked, introduce yourself to the object of your affections again and again and keep refining your pick up moves until eventually this person fell for you, does that make you a romantic or a creep? Is it true love or an elaborate manipulation? The protagonist in About Time, the latest syrup-lacquered rom-com from Love Actually and Bridget Jones’ Diary writer/director Richard Curtis, discovers at age 21 that if he retreats to a quiet place and clenches his fists he can zap himself back to the past and relive any moment of his life.
