"Lacking either ornate production or a pop single, The Idler Wheel plays like Fiona Apple at her purest and that's plenty complicated: she takes no shortcuts or easy turns, her intent somewhat shrouded but never absent. Much of the charm of Apple's music isn't decoding what it all means but learning its internal clockwork, letting the songs take root, so the love songs ("Jonathan") seem sweeter, the braggadocio ("Hot Knife") funnier, the pathos ("Valentine," "Regret") and paranoia ("Werewolf") feeling fathomless".
