Allow me to ignore certain genres
I used MovieLens many years ago when it first started, then stopped. Now I'm trying it again, but see that many of the old features are gone. It used to be possible to exclude certain types of movies (e.g. children's, horror, foreign language, etc.). At this point all I can do when I encounter a kind of movie I know I'd never want to watch is to hide it, which is time-consuming.
