Monster Inc. It's one of my favorite movies, for the plot, for the content and for the memes were made from this movie. Monster Inc. It is an energy company which supplies energy to the city of Monstruopolis, here lives James P. Sullivan aka "Sulley" and Michael Wazowski "Mike", who are the protagonists of this film. One night, Sulley discovers that he had left a connecting door to a girl's room, without saving. So he enters through that door, and returns when he sees nothing that catches his attention. But in reality the girl, named Boo, who was in the room had hung on her back, reaching her world, and thus altering the order in Monstruopolis, Boo takes refuge in Sulley's house along with Mike, then they fight with Randall, who is another monster, for not killing Boo and just returning her home through the door. Finally the girl is returned to her room and Sulley becomes fond of her and vice versa. Good argument for a fantasy story Monste...
