This would be better fit for a wiki
A complete wiki should have a complete list of movies with pages for every movie and the pages for every movie should have links to lists of reviews, and the ratings from those reviews can be used to sort the list of movies, and so can the genre, decade, etc
But this would also have all the soundtracks of the movies and all the books some of them are based on too, there's no reason to fragment it into a different app limited to movies
