Not Another Happy Ending. Karen Gillan is an author whose first quasi-autobiographical book is a massive hit. Her life seems to be finally coming together, but when she gets writer's block on her second, her publisher decides she can't write when she's happy, so sets out to ruin her life and make her miserable again! This Scottish rom-com is nothing particularly astounding, but is pretty watchable and entertaining, bouyed enormously by our Kazza's sheer presence and charisma.
