Top 3 Favorite Dystopian Books/Movies

Hi, everyone. I was thinking about what my favorite dystopian books and movies are and it occurred to me to ask you (my readers) which dystopian books or movies were your favorites. I have read a lot of dystopian books, but there are always some I've never heard of or I've never gotten around to reading. Let me know what your top three dystopian books or movies are and why you consider them your favorites. I look forward to hearing from you all.
