To talk about a website related to films and TV shows, I'd like to talk about IMDb, the full name of the web is Internet Movie Database, it's a page when you can find every movie made in history, the profile of directors and actors, and every movie they did categorized in the role they worked (directing, writting, acting, etc).
Also you can create an account, put a mark on movies you saw, create lists about an specific subject and even write reviews about it. I personally have a list of the movies I watch, every time I saw a new one I go to the web and add it to my list.
I visit the web almost every day, updating my list and reading about the upcoming films, watching trailers and reading the news about differents festivals around the world. It's very flexible because it has a mobile app for Android and iOS, so I can check the web in my free times on my phone.
I really recommend the web to anyone who likes to read and learn about new films and shows, it's like a large encyclopedia of the seventh art.
