‘Unbreakable Kimmy Schmidt’ is a straightforward fish-out-of-water story, but it’s proper feelgood fun. After being rescued from an underground bunker, where she’s been living as part of a doomsday cult for 15 years, the eternally optimistic Kimmy Schmidt (played by the US ‘Office’s Ellie Kemper) decides to embrace the world she had thought had been destroyed. So she moves to – where else? – the Big Apple. Soon she’s getting up to speed on what’s changed, particularly smartphones, selfies and Siri. Cheesy? A little. Soppy? In parts. But whenever the tone starts to turn too sentimental, it’s always punctured by a daft joke.
