Despicable Me 3 picks up shortly after the events of Despicable Me 2. Gru and Lucy are settling into married life, and Lucy is (very awkwardly) trying to get used to her role as mother to Gru's three adopted daughters. The Minions are...well, The Minions.
But just when life seems just about perfect, Gru gets fired from the Anti-Villain League (AVL) when he fails to bring in the notorious child star-turned mullet-headed villain, Balthazar Bratt. This whole scene causes quite a bit of tension in the former villain's household. And more drama is on the way when Gru learns he has a long-lost twin brother, Dru. And Dru wants nothing more than to become as great a villain as Gru was back in the day. The only problem is Gru is reformed. And Dru is just plain awful at being bad.
Hoping to make everything right with his family and the AVL, Gru enlists Dru to help him bring in Bratt. Only Dru thinks they're on an evil villain mission. With all the lies, drama, and impossibly crazy schemes, it's not a spoiler to say this probably won't end well.
Despicable Me 3 wasn't as good as the first or even the second Despicable Me movies. There was too much going on, for one thing. And it just didn't have the heart of the previous films. Almost all the feels that should have been there were sacrificed for gross humor and overdone jokes. Still, the movie had its moments. My particular favorite scene was when Agnes goes Unicorn Hunting. The Minions also got their musical moment in the spotlight. The Minions make everything better.
Overall: A, entertaining film, but not nearly as awesome as previous ones in the series.
