Well, to be honest except for Final Fantasy 4, I haven't played any other JRPG this generation, but I had the feeling most reviews were giving bad scores only because of the unchanged formula and prefered the western RPG. One friend told me he really liked Blue Dragon, and that one received low scores. But who knows, I haven't played them so maybe reviews are right. Anyway, don't let a review dissapoint you, play the game first and then decide.
The problem I have with that is that western reviews don't penalize other genres for having the same formula. Even my best friend remarked on this. He is more an FPS gamer than I am but he even mentioned that FPS games don't get penalized for the same old thing. Call of Duty Word at War is yet another WWII that is essentially Call of Duty 4 with setting change. A setting change to the most tired and worn out FPS setting of all time, I don't see anyone slapping 5 and 6 reviews scores on it.
