People who critique moving pictures fall into 3 general classes:
1. Reviewers - are generally journalists who describe the contents and general tone of a movie, with only incidental emphasis on aesthetic evaluation.
2. Critics - are also journalists for the most part, but their emphasis is more on evaluation than on mere content description.
3. Theorists - are usually professional academics, often the authors of books on how movies can be studied on a more philosophical level.
I'm a film critic and I like to write about films that are exceptional and stand above the rest.
"The role of the critic is to help people see what is in the work, what is in it that shouldn't be, what is not in it that could be. He is a good critic if he helps people understand more about the work that they could see for themselves; he is a great critic, if by his understandings and feeling for the work, by his passion, he can excite people so that they want to experience more of the art that is there, waiting to be seized. He is not necessarily bad critic if he makes errors in judgement. He is a bad critic if he does not awaken the curiosity, enlarge the interests and understanding of his audience. The art of the critic is to transmit his knowledge of and enthusiasm for art to others." ( Pauline Kael )
