If you are a Kodi user you already know that this media center goes way beyond simply managing user multimedia like photos, videos or music. Its features can be expanded and improved by installing add-ons developed by a sizeable community of users who make the most of the open-code license status of the software.
TV series, movies, music, cartoons, training videos...
You can find all this and more on Numbers, a Kodi add-on which offers an online content catalog which can be accessed for free. Once installed, you will be able to browse the categories into which content is sorted (have to say it, they could be tidied up a bit), and you will find collections of movies or TV series, both current and classics like The Sopranos, The Wire or Game of Thrones (can that be considered a classic yet?).
Access to all this is free and content is periodically updated, so we are guessing you won't get through it all unless you have way too much free time.
