Similar Movies

I have a spreadsheet with a listing of similar movies for each movie in my collection. For example 10th Victim (1965) is similar to: |Running Man, The (1987)|Rollerball (1975)|Death Race 2000 (1975)|Condemned, The (2007).

I have this for each of my thousands of movies (I believe the listing was built from allmovie.com way back then).

Anyone have suggestions for using this information to help viewers find a movie to watch? The obvious approach would be for the user look up a movie they like, go to that movie’s information page, and see suggestions for similar movies.

A how-to would be helpful (I’ve only been using Kodi for 2 weeks now). I can easily generate an .NFO for each movie containing the spreadsheet information. But then what?

Thanks for any thoughts.
