The movie has strong positive themes about loyalty, friendship, courage and teamwork. Characters learn lessons about themselves and others. Strong message about enjoying life's joys.
Some tense scenes show the main characters in peril. Some slapstick falls; characters fight/grapple (but no one is seriously hurt). One battle scene turns out to be from a video game. In the 3-D version, a couple of scenes can be briefly scary, like when Buzz's nemesis Zurg is featured. Characters' separation from their friends/loved ones could be upsetting to some younger kids.
Very mild flirting between toy characters.
Mild insults like "idiot" and "shut up."
Several of the Toy Story characters are recognizable brands (like Barbie, Ken, and Mr. & Mrs. Potato Head). And beyond that, the Toy Story franchise has the potential for the most merchandising tie-ins of any kid-targeted movie series. Toys, action figures, books, party supplies, plush dolls, you name it -- Disney's Toy Story characters are everywhere, especially kid favorites Woody and Buzz Lightyear. A large part of the movie takes place inside a toy store; companies/brands like Playskool and Mattel are mentioned by name -- other toy brands depicted include Operation, Tinker Toys, and Mouse Trap.
