Puss in Boots was what I expected - interesting characters, some great laughs (including the Shrek-like humor for adults only), and an interesting backstory. Unfortunately, no cameos from major Shrek characters (I always get a kick out of Gingy).
Antonio Banderas does a great job voicing the "hero" Puss, and the movie provides Puss' history with some good laughs and great images. The big eyes look of the adult Puss is topped by the young Puss, and we learn how Puss received his name and his boots.
Humpty Dumpty is Puss' long-time friend, who becomes jealous of the young hero Puss and betrays him. But, Humpty Dumpty returns with a plan to achieve their lifelong goal - get the goose that lays the golden eggs. Humpty Dumpty has some funny lines and great visual humor. My favorite was Humpty wearing a golden egg costume.
Joining the adventure and rounding out the trio is Kitty Soft Paws, who transitions from Puss' nemesis to love interest. The pair has some great chemistry for animated characters. Their adventures include run-ins with Jack & Jill (not what anyone will expect), magic beans, the beanstalk, and the goose that lays the golden egg.
Overall, kids and adults will love the movie for its humor, cute characters, and action. Puss in Boots is a worthy spin-off of Shrek. And, the movie has a great message about learning from our mistakes, retribution, and making good choices.
