Plot sucked
Just a hugely extended version of a Jack and the Beanstalk panto with the character of Humpty Dumpty thrown in, for no obvious reason? Not enough to keep my interest. Maybe kids would find it OK.
Also they could have inspired themselves a bit more from the actual tale of Puss in Boots from Perrault's fairy tales, about him helping his master marry a princess through his cunning schemes, and killing an ogre etc.
