What are the differences between film reviews and film criticism?
Film reviews are written for the general public by usually journalists or other non-academics and appear in newspapers, magazines or online around the time the film is released in theatres. Their purpose is to describe the plot, characters, director, etc in order to help determine whether or not a film should be seen.
Film criticism is the study, interpretation and evaluation of a film with regard to issues such as historical context, theory or technical analysis. Film criticism is written by academics and is published in books or scholarly journals. It may sometimes address a specific apsect of a ilm or focus on the work of a particul director or genre. Critical reviews may be published many years after a film is released.
