Olympia was made to ind of make Venus of Urbino. Venus of Urbino was supposed to portray marriage, fertility, and having to obey your husbands needs. Olympa does the opposite. Olympia was a common name for pr*stitutes in the time this piece was created and Olympia had a bored look on her face, she was stiff, she didn't wanna be there. Thats why it got so much criticism, because it portrayed Venus, a goddess, as a lowly commoner, as a pr*stitute. A video that explains this well is Vox's video
Not sure if you still need an answer but my favorite character is Remy. He is: Brave, talented, and focused. Since the movie's main character is a rat that can talk, I would say that it is fictional and humorous. A family comedy.
