The only issue I had with the game was the battle system which was basically mashing the X button without thinking so you can stun the big boss before he can one hit kill you.
I like the battle system, but can understand where you are coming from. I'm not using auto-battle and instead inputting my own commands and doing that while needing to switch out paradigms regularly is keeping enough action/inputs to help me enjoy it.
I hear FF13-2 is awful though, even from people who enjoy FF13. I'm hoping that it isn't so bad as I'd like to play through all 3 games (13/13-2/lighting returns). Going to try to do what I did with this and just accept it for what it is and go into it with no expectations.
