Genres and Topics
Series, documentaries and films catering for preschool children. These works usually focus on education, and are didactic in nature.
Topics are sub-genres and/or themes of any kind (romantic comedy, buddy, sports, etc.) that describe the plot of the movie you are looking for. Topics, however, are not keywords. If you search for a topic like "shark", for example, only movies in which sharks play a significant roll will appear, such as 'Jaws'. But not every movie that has a shark in it will be listed.
