Disney and Pixar's Finding Nemo is about a father who goes on an epic journey in search of his taken son. The father, Marlin, is a timid clown fish who pushes his fears aside to bring his son, Nemo, back home. Nemo is taken captive by a dentist and is supposed to be a gift to the dentist's niece, Darla.
The antagonists in the story are humans. We don't really see how having pets is a bad thing. This movie gives us some insight on what animals possibly think when we take one of their own and separate them from their family; animals have feelings and we should acknowledge them. Animals are not mere objects for people's personal gain. The movie also shows a lot of human character and personality traits in animals, such as companionship and stubbornness. Finding Nemo makes the viewers empathize with Marlin after his lost and we cannot help but to cheer for him on his mission.
