Forget the fact that there is little actual gameplay in 13. The story horribly is horribly boring. What makes a Final Fantasy game? The plot and characters and Jesus, it's like they digitized a sleeping aid. I can't say one remarkable thing about any of the characters from 13 because not one of them was remarkable in any way. Seymour, a non-party character from X, had a more compelling backstory, reasoning behind his actions, and character development than any of the party in 13. Yes, it's that fucking bad.
I've been a FF fan for a long time and it's to the point where I'm starting to not care. A Realm Reborn was good but the Japanese, well more specifically Square Enix, are fucking clueless about what makes a game good. It's not Good graphics, a jilted script, and a game which by default makes decisions for you. That's called an interactive movie. This isn't the days of the 3DO.
Have you played Bravely Default yet? Because if you haven't, you should. It's not perfect, and the last half drags on quite a bit, but it's totally worth it.
