I'm gonna blaspheme a bit here, but I personally don't hate any of the FF's. In fact, I liked X-2. /hide in a corner for the barrage of rate-downs.
I also enjoyed X-2. I don't share some of you people's love for 8, which is the only FF I have ever given away to a friend (because I knew I'd never play it again) (Loved the characters and story, but hated the fighting). However, I haven't even purchased 7, which puts it at my least liked FF to date, I suppose. (Loved the fighting, hated most of the characters and didn't care for the story)
Can't really comment on 12 and 13, though, as I haven't played either enough to really give an informed opinion. They came out after FF11, explaining why I haven't given them many hours of playtime.
