The full-throttle assault on reason, taste and human dignity that is this sequel to 2012’s sisters-versus-playas romcom lays on a Vegas reunion for a set of now married or engaged characters almost everyone save the Sony beancounters had left behind. Overcompensating for an absence of honest gags, Tim Story cranks everything – soundtrack, stag party lo-jinks, hollered life lessons on “scoring” – 75% louder than the average UK ear will tolerate: the image of Kevin Hart dancing in his underpants to a Pitbull song may well be emblematic of where the American mainstream is nowadays, but surely didn’t need preserving for future generations to recoil from.
