This seems like a short-term problem. It would be like saying Netflix doesn't have content worth streaming, besides documentaries. A lot of people originally had this opinion of Netflix streaming services, and over time they fixed it.
Fixing movies is a bit more difficult. It requires in some cases larger and maintained budgets, and possibly even eventual increased subscriptions costs, or new revenue models to sustain it. However, all indications seem to indicate this is a path they are willing to go down.
In terms of quality material though, or gaining knowledge in how to improve it, or updating the interface to highlight bigger must watch films vs smaller films, I don't think this is an unsolvable problem for them.
