B elying its diabolical trailer, this Scottish holiday romcom – following heartbroken strangers Jen (Natalie Clark) and Rob (Kenny Boyle) trying to get back to Glasgow from the Highlands – somehow, implausibly, almost manages to win you over. Yes, it has stockings full of direlogue, wooden direction, a pathological compulsion to rattle off every yuletide cliché in existence, and plot turns (bar the final one) visible from space. But saving graces are a heartfelt depiction of the genuine sadness many feel at this time of year, and the Big Katie Morag Energy of Jen’s relentlessly upbeat must-save-Christmas quest.
