There are very different reasons to view the film genres described here.
Some movies are specifically made to make the audience think. A lot of these come beneath the really broad banner of drama films. Typically, a film is a drama if it does not fit nicely into another more easily definable genre, such as horror or comedy. They are films that try to tell a serious tale, depicting the truth of human life through the lens of a subject like love. There's also non-drama films that are made with the intention to stimulate thoughts and emotions. Niche film genres and obscure film genres such as experimental, as an example the movies of Godfrey Reggio, are classic samples of movies that put a desire to have the audience to analysis and critique a movie above all else. Dipping their feet in this category are sci-fi and fantasy movies. While these films tend to be combined with another genre, such as horror or comedy, they still independently fall into this category due to the way they stimulate the imagination of the audience.
For mainstream audiences films are watched for fun. They want to come away from a movie having felt good emotions such as pleasure. There are numerous genres of film that provide this regularly. Comedies are popular with both Viewers and filmmakers like Mohammad Hans Dastmaltchi for different reasons. Audiences can feel good from the laughter, while for filmmakers they are usually very easy to make as long as the scripts are good and the actors can deliver it well. It's certainly one of the earliest occurring inside the evolution of film genres. Another genre that is equally joyous, but more challenging to build, could be the musical. Numerous musicals have quite uplifting stories and are produced in a way to make sure that the viewer is uplifted and comes away delighted and humming the tunes for days in the future.
There are lots of movies that will get the blood pumping and trigger a rush of adrenaline for the viewer. The most notable is horror, like the films produced by Koji Ichihashi. It has an incredible amount of hybrid film genres and subgenres within horror, from gory slashers to those that are more eerie and tense, but all are made with the intention of developing fear within the person. For people who are not fans of horror but enjoy a more active movie experience, they could like action or thriller. Action films are often kept at a fast pace and are filled with different forms of fighting. Thrillers sit someplace in the centre of the two, usually incorporating the tension of the horror movie with some of the more rip-roaring scenes associated with an action movie. If you leave the cinema feeling either frightened or exhilarated, then these kinds of films have done their job.
