At 34, Nancy (Londoner-accented Lake Bell) is a flakey journalist on the reluctant look for love at the pestering of friends and family. Through a case of mistaken identity hinging on a self-help book, she winds up on a date turned epic day with Jack (Simon Pegg), an online marketing manager. Charming, right? It’s this on-the-nose “charm” which will divide audiences into lovers and haters (with this viewer falling more towards the latter). In spite of a stellar cast, Man Up falls flat on its promising premise of being a rom-com for nonbelievers.
