The Secret Life of Pets has pets gathering and enjoying themselves once the owners leave the house, not unlike what the toys did in Toy Story (1995). We have a new foe becoming a new friend (not unlike Toy Story (1995) again). Like many pet-centric movies, quickly the protagonists are pursued by Animal Control, and run into an evil group of pets.
Although the plot may not be too original, most of the supporting characters have distinctive personalities, especially a crazy rabbit. I’d say the movie is quite entertaining and funny, but never reaching the high standards set by the Toy Story franchise.
Note: There is an extra scene during the credits.
