Ah, that one, sorry. A bit too long ago (was merged for Kodi 18 RC1
)
Well, the explanation at the PR explains it. We currently get the one or the other, but we are not able to choose what we want to see.
If there's an overview preset, we will see the overview. If there's no overview present we will see the list of movies with the matching release date.
Unfortunately there's some incompatibility for libraries which are very old (like mine, which started on XBMC 11) where there never has been an option for an overview. Let's assume the following:
I scraped the movies "Bad Boys" and "Bad Boys 2" back in the time (Bad Boys 2 is from 2003). At that time there's was no database option for an "overview". So, if I have exported my movies back in that time and I had the NFO files, thse "set"-section" will look like:
Code:
<set>Bad Boys Collection</set>
So "Bad Boys" and "Bad Boys 2" are both belonging to the set and as "Bad Boys" will be the first movie in that set, it doesn't have anything mentioned like "overview". It's simply not present, because at that time we didn't have an option for that.
Now, 17 years later, I scrape the movie "Bad Boys for Life" and if I export that movie, the set-section will look like:
Code:
<set>
<name>Bad Boys Collection</name>
<overview>2 Films about the cop duo nick named 'Bad Boys', blowing stuff up and crazy car chases. They get the job done but at an expensive cost.</overview>
</set>
So, now we have that overview, but only for one of those movies and as that is not the first one for that set, we will never see the overview as that has to be present for the first movie which was added to the set, which is not the case if you don't change your NFO files or re-scrape the existing movies. The 3rd movie will still be added to the set (as the "old" set-section is still compatible with the new one), but the overview will not have any effect. So you have to change all your NFO files or rescrape all your existing movies to get the overview.
I have to admit that this is done fast for the mentioned set. But now think of movies from the "James Bond Collection"
That's where it might get confusing for the OP, as he might also have sets which display only the overview or other sets where he has the list of movies being shown.
Maybe we can hack some setting in Kodi to be able to let the user decide what he wants to see (will be Kodi 19 only as Kodi 18 will not get new features). But that wouldn't solve the problem for libraries which do exist for years.
Edit:
And it might also be the case, that we don't show the overview if there's nothing for an overview present on the scraping-site. Not sure if there's any case which might match. But if we don't scrape an overview for a movie, because the information provider (TMBD) doesn't have that info, we will still show the list.
