Like bad pennies always turning up, idioms are totally the most pervasive things, possibly, ever. Here’s one that frustrates me: it does what it says on the tin. I dislike this idiom because it probably reminds me of that Monty Python sketch in which I learned “tinny” words were bad, but more importantly because when used in reference to fictional narratives, it feels silly. Saying a whodunit is a whodunit or a rom-com is a rom-com is no defense (nor praise) of writing, storytelling, or creation of pop art. And yet, here is Penny Dreadful, showing up on cable and doing exactly what it says on the tin: being dreadful and doing it cheaply.
