I beat the game and forced myself to play though for the story. xD
I had some issues with the gameplay but the biggest one was probably auto-battle. It felt like it was less interactive and took control away so it made the battles boring for me. I only had to use manual for when enemies were broken to make sure they got launched but that was about it. I liked the paradigm shifting, pretty graphics, and cool Eidolon summons though.
And I still want to play XIII-2 too for the story even though I played the demo and found it dull despite many improvements. lol
