Here's a translation of the reviews (courtesy of finalfantasy-xiii.net):
Reviewer 1 - 10/10
"Although the game is linear until the midway point, the story is substantial, like no FF before it, with its own distinctive appeal. The battles based around changing characters' roles is radical, and highly strategic. The tempo is speedy and you get very excited when fighting strong enemies. Being able to restart battles is a user-friendly feature I'm happy about.
Reviewer 2 - 9/10
"Unquestionably the highest echelon of event and movie scenes. Moreover, changing Optimas on a dime, the varied abilities and being able to use multiple magics at once bring real exhilaration to the battles. That high quality is unfortunately offset by a story that stays linear until the midway point. The lack of gimmicks during the middle of the game also worried me."
Reviewer 3 - 10/10
"The overwhelming graphics expressing every nook and cranny of this unique world, along with the praiseworthy direction, moved me!! The battle system is applicable both to beginners and micro-managers. They progress quickly, and have ratings, so you never grow tired and can always fight with a feeling of urgency. The melancholic story is also so dramatic, you can't tear your eyes away from it."
Reviewer 4 - 10/10
"I doff my hat to the overwhelming graphics and story. Since the game's various systems become denser as the story progresses, you find yourself pulled ever deeper into the experience. The summon battles take careful planning and strategy, so I was frustrated a few times, but the feeling of achievement when you win is something special. You'll be sorry if you don't play this!"
Total: 39/40
