To be fair, "overwhelmed" is how one feels reading the book; we're given SO MUCH all at once. Competing cultures. Strange names. Prophecy. Paul is referred to in 4 or 5 different ways... it's a lot to take in. The movie was the same way. They explain everything, but there's a LOT to explain so they say it once and move on. One constantly feels "behind" and then, at the end, you feel this "wow" sensation of the scale of squeezing all that lore and world-building and storytelling and philosophy into one book.
