How to use a Roku when there’s no Internet

A memory that’s stuck in my head is a day, many years ago, when the internet went down in my apartment for several hours. I was so bored that I started watching all the documentary extras in the Lord of the Rings DVD box set. I enjoyed them, but I was pretty much done with Tolkien for a while after that. In retrospect, I probably should’ve used the time to read the books, not just watch something based on the movies based on them.
