I gave that method of organization a shot once, but things got confusing after awhile: is The Godfather a drama or a crime movie? Is Return of the Living Dead horror or comedy? Should I make a horror-comedy genre to differentiate from the more “serious” horror flicks? Is Hot Fuzz a comedy or an action movie, or a action-comedy in the vein of Beverly Hills Cop? Is Starship Troopers an action movie or science fiction?
I finally gave up and just went with straight alphabetization. Now I can find things easily.
