Yes, it is cheesy. But the voice acting isn't half bad apart from one character (Venille). Besides, ff is always known to be cheesy. I have played every ff game as well and I think this actually less cheesy than VII or VIII. The story is drawing me in which is a good thing knowing how much of it was spoil for me already (I went to wiki page, silly me).
I am in awe of the graphics. I love the environments especially the frozen lake. This is the first time I have seen ff on a high def and it really surprise me how great it look. But I don't like that fact that battle transition into another screen. I liked the ff xii setup more.
All in all, I don't think I mind the linearity of it all like a lot of the people do. May be I am too old, I don't know
.
ps. VII is my favorite.
