If you are mostly interested in documentaries and non-fiction, you might want to consider Curiosity Stream. Available online or through Roku, it costs $20 a year but it has a lot of documentaries on a large number of subjects, such as history, science, technology, nature, civilization, and the human spirit. Some are basic documentaries, while others are documentary series. I signed up for a year. By the time a year is up, I’ll probably have seen everything that I am interested in so I may not renew. Then again, like Netflix, maybe they’ll add enough new stuff to keep it interesting.
