film genres and style

Films are often divided into genres, which describe the typical subject matter - - what the film is about. This is distinct from film styles, which describes filmic conventions which can be applied to any genre. Of course, the more that genres are defined, the more likely that a filmmaker will try to combine, transcend and evade categories, so not every film can be neatly labeled.

A film style is a recognizable group of conventions used by filmmakers to add visual appeal, meaning, or depth to their work. It can encompass every aspect of film; dialogue, cinematography, attitude (i.e., seriousness or lack thereof).
Film style is distinct from film genre, which defines what a film is about - - Western films are about the American West, love stories are about love, and so on. Although some styles are strongly associated with certain genres, a style can be applied to any genre - - Barbarella - is a surrealistic science fiction film, for example.

Obviously each filmmaker develops their own film style, but certain styles that transcend individuals include:

film noir
surrealism
musical film

To be more specific, our film is obviously a drama, isn't it?

But what is a drama film?

"Drama Films are serious presentations or stories with settings or life situations that portray realistic characters in conflict with either themselves, others, or forces of nature. A dramatic film shows us human beings at their best, worst, and everything in-between. " (Dirks 2008)

Our storyline is about a person and his/her difficulties during lifetime while he/she is having a depression. Her/his difficult time comes from his/her surrounding things in life.
