Study as much as you can about the film before seeing it. This will put you in the proper mindset and you will know what to expect. Have a list of all the stars, the director and the producer compiled, along with their most recent projects. This information will help you to put the film into prospective.
Watch the movie carefully. If you feel you've missed something or want to catch more nuances, you may need to see the film again.
Take notes. Write brief notes as you watch the film to remind yourself of the key elements you want to discuss in your essay. Simply write down the things that will jolt your memory, such as: actress in the first scene was awkward with her lines or the opening scene was too dark to see what was happening.
Determine your assessment before you begin writing the essay. If you liked the movie, explain why. If you didn't like it, go into detail. Stick with your theme as you continue writing, using your notes to back up your opinion.
Discuss the key elements of the film. Briefly describe the plot and list the key actors. Bring in the music and how it set the mood, as well as the cinematography, special effects, costumes, acting, symbolism, and anything special that stood out in your mind after viewing the film.
Write your final assessment. Tying in all the elements you have already written, decide whether the film will become a classic or a dud. Tell if the movie was forgettable or if there are scenes that are unforgettable. You may wish to use a rating system based on numbers, with one being the worst and five being the best.
