The synopsis you have written is a bit long; you don’t have to write in so much detail. Try to write a very brief summary about the movie in 100-200 words. The rest of your essay has some good points for discussion but you repeat a lot of the information you gave in your synopsis and describe the same scenes again and again. Try not to repeat yourself which you can avoid by analysing different scenes – you talk about the same scene in the ocean a lot.
