Film review or film analysis?

This might help you:

Review	Analysis
Subjective evaluation	Aid to understanding
Introduce and identify      Title, director, genre, producer, studio, (country), year, running time, actors/cast, rating. The reviewer often situates the film with reference to other work by the same director / main actors, and other films in the same genre.	Simple identification is enough (Title, year, director). Other elements mentioned as necessary
Analyse/sum up the plot	Assume that the reader has a working knowledge of the plot – no summary is necessary unless the plot is your focus.
Discuss the genre Evaluate the acting Broader context	Chooses one or several elements and analyses how they work and contribute to the film (setting, narrative, theme, characterization etc.).
