SEASON FINALE: Em (Emily Mortimer) and best friend and personal assistant Dolly (Dolly Wells) end Season 1, with a poignant episode that leaves lots of room for an interesting and involving Season 2 – but only if producing network Sky, the British source of this series, opts to make more. Two episodes are shown tonight, and the last one, set in a London restaurant, is the one that really demonstrates this show’s potential.
