Film criticism and film review are often used interchangeably, however they are differences between them.
Film / Movie reviews
Film reviews are written for the general public and published in magazines, newspapers or online very soon after the film's release. Their purpose is to describe the plot, characters, director, etc in order to provide a rating or recommendation rather than analysis.
Film criticism
Film criticism is the study, interpretation, and evaluation of a film and its place in cinema history. it is the scholarly and in depth analysis of film published in academic articles and books many years after a film is released; The criticism can focus on a single film, a genre of films, a director's or actor's oeuvre and more. It is often framed through the lenses of film theory.
In-depth criticism and analyses of some feature films or mainstream films, foreign films, independent films, documentaries, etc. may be found in more scholarly or academic publications (e.g. Film Quarterly, Cinema Journal, Film International).
Movie reviews are published when a film premieres nationally so it is useful to know the premiere date. This information can be determine by checking IMDB (Internet Movie Database), the American Film Institute Catalog (films prior to 1971), and the All Movie Guide.
Film reviews are usually written by entertainment reporters and published in newspapers & magazines.
