X + Y
"X + Y" is probably better known as "A Brilliant Young MInd":
Thanks for this feedback. In the future, queries and improvements to the movie collection itself are better sent to movielens-content@umn.edu . We only check the user-voice idea suggestions from time-to-time and it’s easy for a query like this to get lost.
Unfortunately, we currently use TMDB: https://www.themoviedb.org/movie/278236-x-y as our canonical source of movie titles, and they still list the X+Y title. I do see the “A Brilliant Young Mind” title over on IMDB, so you could probably go to TMDB and recommend that as a title update — they are pretty pro-active about allowing community edits. If that changes the title in their database it should show up changed on our database as well…
