Context: A legal drama or a courtroom drama is a subgenre of drama and crime fiction.

Common subgenres of legal dramas include detective dramas, police dramas, courtroom dramas, legal thrillers, etc.  Legal dramas appear in many forms of media, including novels, plays, television shows, and films.
