Good catch! I did some searching and I believe that this is not an actual special or episode that was added. The only thing that I am able to find close to this is a series of fan made YouTube videos... https://www.youtube.com/playlist?list=PLQoiQOFpsHdrUUlNvHd4AqoewQ6kb1pNt and that this episode would be Star Trek Retrospective, Part 8... https://www.youtube.com/watch?v=LB08m-d1hhc Also I would have thought that a special would have been added sooner to a well known show from the 90's instead of being added only 4 months ago. ;) https://www.themoviedb.org/tv/655-star-trek-the-next-generation/season/0/episode/97/changes

Or it's the Retrospectiva Star Trek: la nueva generación/Star Trek Next Generation Retrospective available on Netflix , which seems to be an alternative title for the "Journey's End: The Saga of Star Trek - The Next Generation" special?

Looks like you are correct, don't know how I missed that. Would that mean that we should add that to the English translation?

Yes, but ideally someone with a Netflix subscription should confirm that the retrospective is Journey's End.

Ok, I found some time to borrow someone's Netflix account and watch the episode. And I can verify that they are the same.

Awesome! I removed the duplicate movie entry, moved the data and created an episode group. All that is left to do is re-order the special, but that'll be for another time.
