Uematsu's been on the decline since FF7 IMO. FF6 was his masterpiece and FF7 was his last really strong score. FF8 was a mixed bag, and after 9 & 10 I don't believe that the series's music is anything exceptional anymore unfortunately. FF12's music wasn't stellar, but by and large pretty decent, and no worse than what I heard in 10. At least it didn't have a wretched death metal song as the last boss's music.
I agree with Setzer on the storyline - I really enjoyed it, though I have problems with the presentation and I think that in some ways it doesn't work so well as a video game plot. But it probably has the least scenes out of the entire series that I'd be embarrassed to show my non-JRPG playing friends (which is most of them). I'm starting to think that the spread of the "gamplay is good, storyline and music are bad" viewpoint is becoming a herd phenomenon. I.e. it's true because "everyone knows it's true".
