I was always curious about the DUNE books, but I was never brave enough to attempt to read them. I also knew that there was a DUNE movie, but I did not try it until the night before watching part 2 of DUNE. I just lacked motivation and interests, because I thought it was not that enjoyable. However, when I started to watch it, I immediately regretted not reading or watching it. I was so foolish to underestimate the movie and books. Now, after watching both films, I am motivated to read the books, and I cannot wait for DUNE 3 (I hope it comes out)!
It may seem confusing without any information about DUNE, but just try it, and you will understand and eventually start to love it.
