The series greatest strength are the many characters of which I'm sure people will like based on looks, oh and there's awesome fight scenes too, what's not to love.
Very good interactions as well, I assume they're based on the game so some people have their own groups but still cool seeing which people in different era's interact, overall has a real nice vibe about it which is always handy in an anime. There was also a crazy blue duck/bird/thing with human teeth for some inexplicable reason which was funny.
