I rarely find a movie is available if I search for it.
I did watch Rubber and really liked it. YMMV
You really should! I enjoyed it more than any of the actual TNG movies.
… that being said, movies? There are some we find, I think the 25% number seems about right if we are looking for something specific, rather than browsing for recommendations.
That said, we don’t have cable/satellite, and we use it for kids TV shows. We seem to find a lot of what we are looking for there.
