The plot is barebones, and the moments connecting this Despicable Me/Minions installment with previous entries are light, clever, and don’t disrupt the flow—which is relentless. These are not movies for the easily over-stimulated. Each frame is packed with vibrant colors and erratic movement. The characters are made of rubber, and the decibels they emit are just a tick under a siren. But the whole package is as infectious as the Minions’ devotions to Gru and Gru’s innocent infatuation with super-villainy.
