I use Tiny Media Manager as it is updated very regularly and is a standalone compact program.. It may require each movie in its own folder (as they should be for use in something like KODI). There is software that will convert a folder with individual files into folders with one click. Using KODI alone for a Netflix like GUI works well but TMM organizes each folder locally and you don't need to worry about backing up KODI's library.
