My brother sent the Fr. Barron video about Bob Dylan in China - which is interesting. Browsing around in this series, which I had never before heard whisper of, was this commentary on Tolkien's LOTR.
For those of us who have read a lot of commentary about Tolkien and analysis of his work, the comments seemed rather over-obvious to me at first. Everybody knows that. Yet I recall that only a subset of Tolkien's readers read anything of biography, much less analysis. I can't think of a person I know in the face-to-face world who is much up on that. The many folks I have encountered who engage in discussions about the theology underlying LOTR are all people I know of, not people I know.
So, if you only like to have a bit of that sort of thing, not getting deeply involved in long essays or analysis, this is a good introduction.
