For me XII is probably the worst FF. It's the only FF I couldn't finish. I actually liked X-2 better than XII, which is somewhat disturbing.
The most important things in a JRPG for me are story/characters and fighting system and I didn't like either in FF XII.
The story bored me - the characters had no character/were pretty flat - I hated the fighting system. It felt like an MMORPG without the MMO part.
I can live with a bad fighting system, if the characters and their story are compelling (or vice versa), but when I don't like either, I get bored and stop playing, which is exactly what happened.
I'll give it another try someday, just for the sake of finishing it - maybe I will like it then, but I very much doubt it.
My ranking of FFs since it migrated to Sony:
1. FF VII
2. FF X
3. FF IX
4. FF VIII
5. FF X-2
6. FF XII
I'm still waiting to get my copy of FF XIII, but since all the people who liked FF X seem to love it, I'm probably gonna love it to.
