Jason Segel takes on co-writer and leading-man duties in this entertaining romantic comedy, which sees him reteam with his Forgetting Sarah Marshall and Get Him to the Greek producer Judd Apatow and writer/director Nicholas Stoller. Although crude humour is guaranteed, these guys have a knack for marrying lowbrow gags with affectionate characterisation and some tidy insights into modern relationships. Here, they also benefit from having Emily Blunt as one half of a couple procrastinating over their wedding. She demonstrates a refreshing lack of neuroses, an easy rapport with Segel and does a priceless impression of Cookie Monster. The pair's quarrels over career plans and living arrangements are funny because they ring true, stemming from the pressures of daily life rather than quirks of personality. But there are moments of heightened reality as well, like Segel's regression from city sophisticate to caveman after following his girl to the Midwest. The laughs come easily throughout and, despite its dragged-out ending, this movie has characters you'll enjoy spending time with.
