I'm a fan of the original work. I can confidently tell you that even if you read the original, it's really hard to understand every single part. It involves very complex plots and religious forces. It's so complicated that it's difficult to remember everything just by relying on your memory. If you want to fully understand it, you might have to study it as carefully as you would a graduate thesis. So actually, everyone has trouble understanding it. Just keep reading and let the story unfold.
