The story is not easily the worst thing about it, it's also easily the worst story that appeared in FF, ever 
20 hour hallway? Try 45. Gran Pulse is just a wider hallway with nothing to do but kill monsters. Replaying FF XIII though? +1. I could never do that. I can talk forever...
Disappointment of the generation? I'd say!
