I didn't buy it day one because I was very skeptical. Instead, I bought Heavy Rain and God of War III.
A couple of days I ago I got a good deal for it and i got it with low expectations, just as a token of appreciation for early wonderful Final Fantasy experiences, and boy, I'm so glad it all happen like this. I'm strongly impressed and having the best time with it and I hadn't even reached the famous 11th level.
I love the story, I love the characters and I love the battle system which is pretty different from traditional jrpgs. Its visuals and music make it an outstanding and beautiful experience. I couldn't be happier.
I am still waiting to make my final veredict though I believe that media and some users failed to appreciate this game. Too concerned on either it delivered the same experience through the traditional tools or not, they were unfair to judge the game regardless of what they had preconceived a Final Fantasy should be. No towns? No "freedom"? Too linear? Well then, the problem is you were expecting Oblivion or a Shin Megami Tensei game. This is no sandbox, thank god it's not. Is different and fresh. Take it for what it is and enjoy. That's what I'm doing and I couldn't be happier with Light, Snow and company.
