I have read over your breif, and I fully understand what your website needs and the functions you are wanting it to have, If you choose me to build the website, I will most probably be able to have the website up in 2-3 days although I have chosen four days this is to keep me safe in case I run into unexpected errors.
I will set it so you can give the Film, TV Series (or anything else you choose to review over time) a rating from 1 - 5 stars, with a custom plugin I will also allow your visitors to give there own opinion on the chosen review, and they will also be able to leave a star rating.
