I usually love this genre and IMO the graphics were great throughout this game.
However it did seem to be slightly lacking something. I couldn't even pinpoint exactly what. It seemed to require quite a bit of grinding which I also usually don't mind in RPGs, however in this one it was more noticeable and I felt my mind drifting to my work that I was putting off doing by grinding instead ;)
And yes, the A button did seem to need to be pressed a lot. Again, perhaps it was just more noticable because something else was lacking.
If you enjoy the battle system specitfically, then perhaps give Bravery Default a shot. It uses a similar system of weakness / strong attacks. The characters are also a little more fleshed out.
But I do plan to revisit the game again. I must have missed some game mechanic surely!
