1- Movie Sets (from TMDB)
a. Why don’t you but one more filter for movie set since each set has it’s own number in tmdb so it will be accurate and easy to follow.
Coollector has its own database, completely unrelated to TMDB, so we don't care about numbers in tmdb.
Also Coollector makes a clear distinction between movies and videos. Our database of movies contains only movies, but you can own a video which is a pack of several movies. Tell me if I'm not clear enough.https://www.coollector.com/help.html#packs
2- Exclude genre
a. In case I need to check 2019 movies all genre expect documentary (no such options)
Above are all personal decision and all depends up on you and your view as well
I never added that option because I don't want the interface to look too geeky (with includes, excludes, regular expressions, etc...).
