Think about how many times you search and search through your Netflix feed to find something you would like to watch. Netflix has an algorithm that will show you suggestions based on what you have watched before, but this new hack will help you find EXACTLY what you want to watch.
Netflix fan site, What's On Netflix has a helpful list of codes that can reveal a multitude of narrow categories and category combinations that Netflix doesn't always reveal.
By using this link: http://www.netflix.com/browse/genre/INSERTNUMBER and then simply insert the number of the specific category you want to view from the list of codes from What's On Netflix.
All set! I would suggest bookmarking that site so you can reference it again and again!
