I found my play-through was a very enjoyable 60 hours and that the game, while not the best FF ever, which I award to FF X, it is very good. And stunningly pretty.
Other peoples complaints are another man's positives. I for one liked the slow burning story which I think was good, the linearity of it, the battle system was good and a nice change making the battles faster and more exciting and the voice acting was good, except from Vanille for about the first 5 hours and in battle as she squeaks a bloody lot and during the first 5 hours, her accent goes from Aussie and into accents I've never heard of. The VO actor gets it right eventually but many people probably wouldn't be able to stand it. I nearly didn't but I persevered and was happy to hear her stick with the same accent and the characters are likeable, Hope and Sazh are more so due to plot twists which I won't mention here for spoiler reasons .
But the things I liked may well be another persons dislike. Looking back over this thread, this is obvious. Different strokes for different folks, I guess. Just rent/borrow it to find out.
