Add a filter to hide/show movies on that are included on [dropdown menu of your lists]. It would be helpful to set aside movies you can't find (in the second (3rd, 4th) tier of the watchlist, to be reviewed at a later date), but still exclude them when you're trying to search for movies you haven't seen, and aren't on your watchlist. I have a lot of movies I want to see but I can't find, and I have to pick between them clogging up my watchlist or clogging up the movie search results.
And if you do it by list, people can make up whatever they need. I can't think of a use for more than 1-2 off the top of my head but..
And you could use it to exclude anything that's on any of your lists..
Can also function as a way to block movies that users are not interested in seeing from clogging up the results.
