The feel of combat is incredibly polished, the cutscenes are immaculately produced, and the music is suitably emotional or heart-pounding when it needs to be.

As for the narrative... up through the Bahamut fight it's generally good, although not exactly what I was expecting. After that, you spend hours doing tedious crap only tangentially related to the main story, and then it turns into a bad shonen anime and stays that way until the end.

Also, it's a good thing that the combat is so good because it's the only meaningful gameplay system across dozens of hours. Not even a hint of dungeon-crawling with exploration/puzzle-solving, or anything else really.
