Question: How do I judge what style a film is? 

Answer: it requires some intensive film viewing in the past years matched  with critics reading .If you are snobbish enough or against mainstream movies,commercial work-out here are some sites you can check out critics .Also you can trust other people's opinion on different blogs or www.imdb.com.And finally you'll see that you can determinate in the end the style of one movie which is not always about the genre:comedy,drama,romance but also about the realism,purpose,playwright.it's not tough especially if you love movies.Why did i say intensive film viewing for a while: because after some time you'll define your style and become quickly bored with the same plot or cliche lines and in the end you'll be your own sleuth for a new good movie.
