Using a combination of live action and CGI that will give some audience members PTSD flashbacks to the recent Marmaduke (hold me), director Brad Peyton has been charged with following up the 2001 original with the sequel no one was hoping for — in pointless 3-D. The usual pop-culture allusions are meant to keep moms and dads grimly entertained, but their kids will be casualties of the overcrowded whiteboard of a plot. A hapless police dog named Diggs (James Marsden) is recruited into a doggie underground to help stop Kitty Galore (Bette Midler), a hairless cat embittered by the industrial accident that uglified her, from taking over the world. A hater of both dogs and humans, Kitty has gone rogue and apparently learned how to launch a satellite into space. Cats and dogs (and pigeons and Christina Applegate) must work together to deliver every pet-related groaner imaginable, within 85 minutes.
