What is a good Film?

Most people often judge a film on the basis of whether it appealed to them or not. Accordingly, they call it Good or Bad. Even Film Critics do that, but is that really the right way to judge it? You may not be the intended audience for the film. You may not like the genre of the film. You may be opposed to its political views. You may not like its message. All these are legitimate reasons for you not to like a film but that doesn't make the film itself good or bad. In my opinion, the only criteria by which a film should be judged as good or bad is whether the filmmaker was effective in communicating through the film what he/she intended to say and whether the filmmaker was able to evoke the desired emotional reaction through the course of the film by his/her skill in telling the story. If the purpose of the film was to scare the audience and if it does so effectively, then it is a good film even though you may not like the horror genre. A comedy should make you laugh, a thriller should keep you on the edge of the seat, an erotic film should get you aroused, a tragedy should make you cry, science fiction should make you wonder and an issue based drama should really make you think about the issue. So a film should be judged without any personal bias for or against the genre of its content.
