I think the game was good. Though lot of people have different expectations. And the game development can't work on all of them. And it makes things a bit harder. And on that note you can see that if we were to be understanding on the execution part. Not all games can be good all the time so people have to adjust.
I think the game is very short when you compare it to other Final Fantasy titles. I think their main goal with this is to attract more people in the West and expose them to the Final Fantasy franchise. For me though, it is a nice change from the classic turn-based system because I really like Kingdom Heart's gameplay and it's nice that Sqeenix is going through this route.
