There are very different reasons to view the film genres described here.
Some films are specifically made to really make the audience think. Many of these come beneath the extremely broad banner of drama movies. Typically, a film is a drama if it generally does not fit nicely into another more effortlessly definable genre, such as horror or comedy. They are films that attempt to tell a serious story, depicting the truth of human life through the lens of a topic like love. Additionally, there are non-drama films which can be made with the goal to stimulate thinking and emotions. Niche film genres and obscure film genres such as experimental, for example the movies of Godfrey Reggio, are classic examples of movies that put a wish to have the audience to analysis and critique a movie above all else. Dipping their toes in this category are sci-fi and fantasy motion pictures. While these movies tend to be coupled with another genre, like horror or comedy, they still independently fit into this category due to how they stimulate the imagination of the audience.
For main-stream audiences movies are watched for entertainment. They want to come away from a film having felt positive emotions such as happiness. There are numerous genres of movie that provide this on a regular basis. Comedies are popular with both audiences and filmmakers like Mohammad Hans Dastmaltchi for various reasons. Audiences can feel great from the laughter, while for filmmakers they are often very easy to make as long as the scripts are good and also the actors can deliver it well. It's one of the earliest occurring inside the evolution of film genres. A different genre that is equally joyous, but harder to build, may be the musical. Many musicals actually have quite uplifting stories and tend to be made in a way to make certain that the viewer is uplifted and comes away pleased and humming the tunes for days in the future.
There are many movies that can get the blood pumping and trigger a surge of adrenaline for the viewer. One of the most notable is horror, for instance the films created by Koji Ichihashi. There is an amazing number of hybrid film genres and subcategories within horror, from gory slashers to ones that tend to be more eerie and tense, but all are made with the intention of making fear within the individual. For those who are not fans of horror but like a more active movie experience, they may like action or thriller. Action movies are generally kept at a fast pace and are full of various forms of fighting. Thrillers sit somewhere in the exact middle of the two, frequently including the tension of the horror movie with some of the more rip-roaring scenes connected with an action flick. If you leave the theatre feeling either terrified or exhilarated, then these types of movies will have done their job.
