I enjoyed the previous two Despicable movies. I liked the Minions standalone movie just fine. But… I dunno… this one left me kind of cold, wishing I hadn't bothered. There are occasional chuckles, but overall, meh.
Anyway: the refored despicable Gru is assigned to thwart the evil schemes of Balthazar Bratt, a child star from decades past who's decided to continue his bratful ways by (what else) a life of spectacular high-tech crime. Gru fails, is fired, and gets sad. But he discovers he has a long-lost brother, "Dru", who is an unreformed villain. And… zzzz.
Yes, cute kids. Minions. Some clever sight gags. Something seems missing, though, and what's left is the usual transparent motive: a by-the-numbers sequel whose sole cynical purpose is to shake some dollars out of the wallets of fans of the previous entries in the series.
