Rick Burin’s review published on Letterboxd :
Wine is probably the most boring subject on Earth, so how come Payne’s film about a lonely, bitter best man (Paul Giamatti) taking the soon-to-be-groom (Thomas Haden Church) on a week-long tour of vineyards is so bloody good? Perhaps because of Giamatti’s astonishing characterisation, which imbues an arrogant, self-destructive, self-hating pseud with a completely disarming humanity. Or perhaps because it’s not really about wine at all, but love and friendship and the choices that people make that end up deciding and defining their lives. It’s the antithesis of formula filmmaking: incredibly entertaining, but also about something, and featuring – quite unexpectedly – a handful of brilliant sight gags.
