Toss together every romcom cliche with rejected music from 50 Shades of Grey and you'll get this predictable movie about two selfish people who deserve each other. It's got all the familiar favourites; a broody man who is changed by love, an English class debate between a half-hearted feminist and a guy who doesn't believe in love, five seconds of resistance before they fall in love, wisely disapproving family and friends, etc. The cherry on top is that he was just doing it all on a bet but - get this - he developed real feelings for her.
