I dont know. Especially in the middle part the story keeps getting more and more confusing and then at the end its always straightened out by "Hey its a paradox!" That is not very exciting storytelling.
I am not one of the XIII haters as you can easily see with my avatar. I really like FF XIII and I thought that XIII-2 was definitely not a bad game either. In terms of gameplay and player freedom XIII-2 is actually way superior to XIII and it feels more versatile and fluid.
however my big gripe with XIII-2 is characters and story. Compared to XIII, the characters are downright lame. Okay not FF XII-lame (FF XII is a great RPG but the characters really are some of the worst in FF history except maybe Ashe and Fran) but they are really dull for a FF game. Nothing like the in my opinion great cast in XIII. To have the characters from XIII featured only briefly in XIII-2 (particularly Lightning who is the heart of that series. The best story moments in XIII-2 are the ones featuring her) was a really bad decision as well.
And the story of XIII-2 was really dragging and especially in the middle part was bordering on downright boredom. No tension, no big emotion, no epic scale. There was a review on RPGsite back then who REALLY summed it up when they wrote that FF XIII-2 has the potential for many epic and iconic moments but then it doesnt deliver in these moments and just lets them pass. Thats EXACTLY how I felt about it too.
Say what you want about FF XIII but that game had an epic scale and really big, iconic moments. FF XIII-2 was completely lacking that scale and that epicness. Just compare it to things in XIII like the Attack on Eden or the Palamecia stuff. The action in XIII was on a whole different level.
Granted XIII-2 begins with an opener that is probably my most favorite FF opening ever. That attack of Caius and his battle with Lightning in Valhalla was AWESOME. Now that was really huge and epic. Unfortunately once Noel and Serah leave New Bodhum that level of grandeur and magic vanishes almost completely and makes way for a confusing, flat drag of a story.
the middle part is the worst, that was the first time ever in a FF game where it became straining for me to continue playing. I never had that before with a FF game. In that phase only the great gameplay and design kept me going.
This thankfully then changed massively again once you reach the Dying World. From that point on the story soared to heights again. When Lightning arrives to explain it all to Serah and then the final battle in Valhalla, not to mention that kick ass shocker of a Finale that literally punched me in the gut and rendered me speechless and really made me incredibly emotional - thats what I want from a FF game.
But an amazing Beginning and fantastic 3rd act isnt enough. So bringing back Lightning as the main character and bringing in the main cast from XIII again in greater roles and make everything bigger, grander, darker, more epic with a completely new world and dive into the mythology (which is one of the best things about XIII) and gameplay was definitely the right choice in my opinion. the XIII/Lightning-haters sneer at Lightning Returns in prejudice and contempt but I am massively looking forward to it since I believe it has the potential to really deliver that emotion and epic scale again that XIII had and at the same time give us all the stuff we missed in XIII in terms of a great explorable world, player freedom, classic RPg elements, tons of sidequests and challenges etc.
I think LR will be a really proper finale and with Lightning back at the steering wheel I think it will be much more exciting then XIII-2 was and not make it hard for me again to stay through a story that just drags along in boredom for a good chunk of the game.
