I loved it for the storyline and characters, however gameplay could have been much better. I think Square-Enix has yet to get the hang of action RPGs. (FF13's combat system better be as awesome as it looked in the trailers) Like the DMW system, it was basically a slot machine that you had to stare at in the middle of battles.
However it did an amazing job at tying in with the original story and fleshing out the backstories of side characters. This may be heresy, but I found Zack to be much more likeable as a protagonist than Cloud ever was.
Also, KICK-ASS SOUNDTRACK!
