It is known that the new Plex Agents provide better metadata results.
The assignment and download of metadata is much faster but to be honest the quality isn’t any better than pulling only from TheMovieDB or TheTVDB.
I get hundreds of posters with a horrible quality and those posters aren’t even allowed to be uploaded to TheMovieDB or TheTVDB. And I cannot disable a option so I stop pulling those ■■■■■■ “artwork”.
Actual issue that shows very well why the new Agents aren’t better (beside their much faster assignment and download):
1st result: IMDB
2nd result: TheTVDB
3rd result: TheMovieDB
The result from watch.plex.tv isn’t even shown … but it should be the only result and be the correct one.
The problem is that Plex incorrectly matches with that student film that can only be found on IMDB. The reason for that probably is that Plex and IMDB thinks the movie was released in 2020 while it was officially released in 2021. IMDB uses the year of the first appearance of a movie (eg. a festival) while every other database uses the first official appearance in a typical theater / cinema.
It doesn’t matter if you prefer the IMDB way or the TheMovieDB / TheTVDB way. The problem still exists whatever you prefer.
It’s probably impossible to change the date of every single IMDB entry and change how IMDB works, thus the only solution would be to ignore IMDB for matching purposes if there is a match in other databases.
While I trust IMDB more with the more technical data and background information I much more trust TheMovieDB / TheTVDB with correct “surface data” like localized title, release date, actors, cover art.
Ideally the data of all three databases would get consolidated into watch.plex.tv and Plex only pulls from there. Then we would at least get a correct match with maybe wrong data, but that data could be easily updated. Sadly, we as users cannot even submit a info about wrong data or anything.
