Jason Segel screenwrites a film where the protagonist gets to be naked and hug Kristen Bell and then Mila Kunis. And have a montage of sex scenes with various hot women. And then gets himself cast as the protagonist. You have to hand it to the guy - he isn't shy. But, in his defence, he can write. This is a funny, well-acted film that evokes great performances from the ensemble cast. Love him or hate him, Russell Brand riffs brilliantly off his own persona here. Mila Kunis is naturalistic and manages to inject range into her character, with sympathy, rage, pity and anger all brought to the fore at various points in a plausible display that never reaches. There is hardly a missed beat here; even minor characters such as the best friend's wife, only ever seen on a Skype screen, are either cute or laugh-out-loud funny. Good fun, and bears repeat viewing.
