Common Sense Note
Parents need to know that A Monster in Paris is an animated period adventure about a science experiment that turns a flea into a huge "monster." But the flea, who is later called Franc, is as gentle as can be and will teach kids the importance of not judging people based on their looks. There's some gun violence and a frightening climactic battle between a meanie with a loaded gun and the "monster" and his friends. Kids who pay attention will get glimpses of Parisian landmarks and will value the movie's messages of tolerance and friendship.
Sexual
Content
A couple of kisses between couples who flirt through most of the movie.
Violence
At first the "monster" can seem scary, but he's quickly revealed to be harmless. A climactic confrontation involves a vehicle chase and then a frightening scene at the Eiffel Tower, where an armed villain shoots at people and the monster. A woman is nearly choked and another is held threateningly off the side of the Eiffel Tower; she almost plunges to her death. The monster falls from the Eiffel Tower and is momentarily presumed lost or dead.
Language
A few instances of exclamations such as "Oh my God" and "Jesus!" as well as insults such as "stupid" and "idiot."
Social
Behavior
There's a great message about not judging anyone by his or her appearances, and how true friends stick up for each other and help each other out no matter the wacky circumstances. Everyone needs a friend.
Consumerism
Not applicable
Drugs / Tobacco /
Alcohol
There are adults drinking at a dance/concert lounge, but it's unclear whether the drinks are alcohol or not (presumably, being Paris, it is wine).
