Let’s give directing siblings Jay and Mark Duplass a hand for taking Fox Searchlight’s dime and giving them back a cringe-comedy about a likeable schlub (John C Reilly), his new dream girlfriend (Marissa Tomei) and her vengeful, clingy adult-olescent son (Jonah Hill) that’s essentially an ever-so-slightly polished Duplass brothers movie. You can spot tiny concessions – a moratorium on lovey-dovey montages, please – but the directors’ offbeat, underground-ish sensibility punctures the material’s mainstream qualities while still keeping things palatable. It’s the rare tale of Oedipal one-upmanship that feels charming, comically sharp and creepy in equal measures, helped by actors tuned in to the filmmakers’ gentle oddball frequency. Neither Reilly nor Tomei have ever seemed so effortlessly funny, and whoever thought to cast one of Judd Apatow’s regulars as a dysfunctional, disturbed manchild should be dubbed a genius.
