By Michael O’Sullivan, The Washington Post Like yet another cold, sugary soft drink dispensed from a vending machine, the animated sequel “Despicable Me 3” is only satisfying in direct proportion to one’s thirst. If you are someone for whom a wait of two to three years between installments of this popular cartoon franchise — which includes the 2015 spinoff “Minions” – is way too long, then this latest chapter in the saga of supervillain-turned-crimefighter Gru (voice of Steve Carell) and his suppository-shaped yellow henchmen will fill that aching void, even as it stokes the hunger for “Minions 2” (due out in 2020). For others, “Despicable Me 3” is just another swig from the same can of calculated comedy. Despite the addition of an interesting new character, Gru’s long-lost twin brother, Dru (Carell), the ingredients are familiar.
