Folklore is not even a RPG. Like I see it, gamers put everything that could be a RPG but isn't at all in the Action RPG genre, fair enough. That's where Zelda, Folklore and others are put, but none of them are RPG. I suppose Mass Effect is an Action RPG too.
As for what makes a JRPG great, that sure enough is not a typical story that has nothing mindblowing.
Every very good RPG has a very good story, some of the best have really impressive stories.
Blue Dragon clearly does not have that. I wonder how they'll rate Eternal Sonata, which is very lacking in story too.
