The amount of people who like Code Geass out number the people who hate it with a passion. I recall a thread of Geass the other week that received 450+ replies in its first hour. If that's not popular on /a/, then I don't know what is.
Also, you're getting the words hate and like mixed up. Nobody really likes Code Geass. Everybody knows the show is questionable. But at the same time only a few people on /a/ hate it with a passion.
