The Hobbit movies sucked, they were just money grabs. I didn’t even watch the third one.
Just from an easier to read perspective, I’d suggest reading The Hobbit first, then moving onto the trilogy. The Hobbit is lighthearted and fun, and sets the world up for the darker and more complex trilogy. But you don’t have to read The Hobbit first or at all to be able to understand the trilogy.
If you enjoy these four books, there are more world building books of Tolkien’s, like The Silmarillion.
Not as a bundle but I bought and read A Series of Unfortunate Events and Harry Potter as they came out. It was so exciting to wait for the next book to be written and then translated and published.
