Diaz plays career woman Joy, who decides to let her hair down in Vegas after being dumped by her boyfriend. There, she meets Kutcher’s likeable layabout, Jack. A few hours and many tequilas later, they’re husband and wife. The next morning, annulment plans are shelved when Jack wins the jackpot using Joy’s quarter: if they divorce, she might get half. However, a judge freezes the winnings and orders the bickering pair to make a go of their marriage.
And so this odd couple must live together and play happy families for their psychiatrist (Queen Latifah). Much sitcom humour follows, mostly drawing on well-worn gender observations: she spends ages in the bathroom, he pees in the sink and so on. Sometimes, the accompanying dialogue is snappy enough to raise a laugh. More often, the humour comes from another source: the Best Friends. Lake Bell steals the show as Joy’s mouthy mate, Tipper, who develops a love-hate relationship with Jack’s misogynist pal who is actually called Hater (Rob Corddry).
In fact, a comedy about these two fighting like cat and dog would have been much funnier. As it is, it’s a bland comedy punctuated by the odd witty moment. The inevitable romance is so routine it barely merits a mention.
