You'll find a variety of movie genres when you watch free movies online. Just log on to any video streaming site and choose from among the categories to get a list of all movies available in a particular genre. Aside from comedy, action, adventure, drama movies, and fantasy movies, some of today's popular movie genres include the following.
War Movies. War movies depict courage, humanity and heroism in the midst of strife and adversity. They can also be filled with drama and make strong political statements. War movies may or may not be heavy on special effects, but they usually feature spectacular battle scenes that explore the grisly nature of war and its deadly aftermath.
Teen Movies. Quite clearly, these films tackle the various themes that preoccupy today's youth-school, family problems, friendship, teenage romance, growing up and battling one's fears or insecurities. Of course, there stereotypes such as the popular girl, the jock, the rebel, the geek, the outcast, the cheerleader and the star player, the average girl / boy, the girl-and-boy-next-door, and the new Girl / boy.
Science Fiction Movies. These films explore the frontiers of our civilization, science and technology. Sci-fi movies bring viewers to fantastic places like far-flung planets and parallel dimensions. A lot of sci-fi movies are set in a chaotic and dangerous post-apocalyptic world that is vastly different from the world we live in. There may be elements of time and space travel, encounters with extraterrestrial life and the struggle for freedom against tyrannical invaders, human and alien.
Mystery Movies. Unsolved crimes and political conspiracies often provide excellent plot points that can leave viewers guessing well after the movie ends. Mystery movies either fall into an open or closed format. An open format reveals the criminal at the beginning of the film as the story is retold, while a closed format is like a typical whodunit detective story which tracks the protagonist's pursuit of the suspect whose identity is typically disclosed in a totally unexpected fashion.
Documentary Movies. These are usually shown in cinemas and movie festivals but are also released in DVD format. You can find a lot of documentaries if you happen to watch free movies on video streaming websites. Documentary films tackle various social and political issues in-depth. Some documentaries follow the lives of certain people to establish a character portrait. While most documentary films depict "real life" and "real people," quite a few fictional narratives are actually shot in documentary style for a more convincing effect.
