recommendations for a robust movie catalog/organizer app?

ok, so we’ve got a bunch of movies in AppleTV (desktop), things we find on Netflix, Prime, old favourites we actually own on DVD, etc. we’re looking for a relatively robust movie cataloging app that will grab artwork, plot summary, year of release, maybe cast and crew info (bonus!), all that stuff, for a given title. we’re not trying to organise actual media, just information about a given item.

we pretty much need to have custom “folders” — drawers, shelves, buckets, lists, whatever flavour they come in — and being able to sort by custom tags would be a good thing too.

a nice search tool would be great — by year, by cast/crew, by genre, for examples — as would the ability to export to some human readable and transportable form (maybe CSV or similar) so our efforts aren’t locked into a single app (in case the inevitable happens).

freebies are lovely but we’re willing to pay for this too so no restrictions there. subscription is okay as long as it’s not crazy expensive.

i hope that’s not a bunch of outrageous demands. we’re searched around and strangely it appears to not be something that’s reviewed/talked about much in recent years, thus the query.
