I'm not sure if you're serious or not, but if you really don't know, Google up the best reviews of "Cats 2019" and delight in the glorious train wreck. Some of the better quotations include: "Will haunt viewers for generations." and "To assess Cats as good or bad feels like the entirely wrong axis on which to see it. It is, with all affection, a monstrosity."
Just don't actually watch the movie.
I've actively avoided reading the Brian Herbert stuff because I tried to read a Kevin J. Anderson book once and it nearly gave me an aneurysm.
