Since his girlfriend dumped him, loans clerk Carl Allen (Carrey) has been saying ‘No’ to everything. Then he attends a seminar given by sleek self-help guru Terrence (Terence Stamp) - “Invite Yes into your life, because it will RSVP, Yes’ – and resolves to ‘Yes’ to everything. Very soon he’s snorting chilli sauce, learning to speak Korean, getting a blowjob from an amorous elderly neighbour with(out) dentures and attending Harry Potter parties thrown by his nerdy boss, Norm (Rhys Darby from ‘Flight of the Conchords’). At a gig by avant garde rock band Munchausen By Proxy, Carl meets and falls for the band’s cute, kooky and free-spirited lead singer, Allison (Zooey Deschanel).
Allison, who also runs a jogging and photography class, thinks their romance is a shaky proposition; but Carl has signed the pledge, so he whisks her along on a string of madcap adventures. But when the truly spontaneous Allison discovers that Carl is merely following a programme, she questions his love for her. Director Peyton Reed’s direction is slick, but each episode feels like a sitcom skit. And when Carrey’s hyperactive comedy shtick gives way to drippy life-lessons, earnest humour gives way to cloying sentimentality.
