CST_ Dreamworks presents an animated film directed by Tom McGrath. Rated PG (rude humor, mild language and some action). Running time: 107 minutes. In theaters and streaming Friday on Peacock. The Dreamworks sequel to 2017’s (checks notes) Oscar-nominated “The Boss Baby” again pushes a simple, funny but difficult to elaborate on image — a baby in suit — to zany extremes. It was a good enough conceit for Marla Frazee’s original children’s book; toddlers can indeed be tyrants. But each movie has hyperactively swaddled that thin premise with a frenetic, over-plotted, off-the-wall cartoon blitz. Director Tom McGrath (the “Madagascar” movies) returns for “The Boss Baby: Family Business” (in theaters and streaming on Peacock on Friday), and fast forwards to adulthood. Older brother Tim (James Marsden, taking over for Tobey Maguire) has grown up to be a stay-at-home dad married to the high-powered Carol (Eva Longoria), with their science-obsessed, high-achieving daughter, Tabitha (Ariana Greenblatt), and infant Tina (Amy Sedaris).
