The problem is your lack of familiarity with the English language. Specifically, how to write a movie review. You should try to read some of the professional reviews online to get a better idea of how such essays are written. Everything is summarized and focused on only certain aspects of the film. If you can avoid trying to exaggerate your comments, you will be able to avoid repeated statements such as:
I've recently sat through and watched from the beginning to the very end without averting my gaze from the screen
Being over descriptive in this section is what hurt the presentation. It is enough to simply say "I sat through from beginning to end."I know you are trying to involve the reader in your experience, but that is not required when writing a basic movie review.
When reviewing the character development, you must refer to the character by name, then the actor's name. You only mentioned one of the 2 actor's names in this presentation, Jennifer Lawrence being the other cast member in the film, and did not mention their characters names at all. There is a lack of proper acting analysis in the presentation that would have helped you review the actors approach to the role. The camera man, director, and scriptwriter's work all lack highlight moments that should have been the focal point of your review for each of these people's participation in the movie. The plot summary could have been better presented within the 170 word count as well.
