Which storyline? I enjoyed that of XII and XIII, even if they were patchy in some places the general plot was good enough for me. XII's real issue was that there was so much to do that you forgot the storyline on occasion, while in XIII it was the opposite - everything was story. Perhaps pacing is the real issue, rather than storyline. Storyline itself... that's more just some didn't like it than all didn't like it. Which can be said for a large number of Final Fantasy games.
