If you’ve always wondered what your pets are up to when you’re not around, you’re in luck, because The Secret Life of Pets was a very funny movie about just that subject, and you can watch it any time you want. The Secret Life of Pets 2, on the other hand, is a mediocre retread of the original, with a few good gags but very little reason to exist, aside from temporarily distracting children and putting their parents to sleep.
The adorable lapdog Max, voiced by Patton Oswalt (taking over from Louis C.K.), thinks his life is just about perfect. He and his dog roommate Duke (Eric Stonestreet) are as happy as could be with their owner Katie (Ellie Kemper), until she meets a nice guy and has a baby, Liam, which proceeds to make Max a nervous wreck. At first he’s afraid the baby will hurt him – which it often does – but then he develops an affection for Liam, and he becomes absolutely terrified that anything will hurt the child.
