In an excruciatingly embarrassing opening sequence worthy of the notorious warm apple tart shag in American Pie, the star of both somewhat infantile romantic comedies, the charmingly gormless Jason Biggs, proposes marriage to his sweetheart dressed as cupid in the middle of a crowded restaurant, and then watches with disbelief as his girlfriend’s response is to drop dead on the spot. This supremely silly set-up in place, stand-up comedian Michael Ian Black’s writing-directing debut then proceeds to a second scene in which Biggs’ eternally besotted nerd is convinced by his exasperated best pal to get over the dead girl by proposing marriage to another, living one. Which he immediately does, not expecting Isla Fisher’s winsome waitress to say yes. Thereafter the film rambles breezily along as the unlikely couple do the courtship thing - meeting the parents, moving in together, learning each other’s names - in 48 hours flat.

The leads are likeable enough, and there’s a modicum of chemistry between Biggs and Fisher, but this nuptials rom-com has much that is old and lame and nothing that is new and fresh. The over-egged double opening gag merely highlights the film’s lack of decent jokes and failure to say anything interesting about romance.
