While the Minions themselves might be almost impossible to tell apart, their franchise is one of a kind: it is the only one around that keeps getting better. It would be tempting to describe this deliriously animated, unreasonably funny seventh dispatch from the world of Despicable Me as the jabbering little nuisances’ Citizen Kane. Except the film itself – a frenzied comic adventure in which the Minions take on early Hollywood (and, eventually, some monsters) – gets there first.
