Impressive to say the least
The first thing you have to notice about the movie is the incredible graphics. The effects are spectacular and the two things the people over there at Square Enix really care about and focus on are the hair and the clothes of the characters which is the reason for the 10 on the graphics part. And the fighting scenes just leave you wanting more and more. For that i give it a 10 at "gameplay" which should be called "movie experience".
The sound? well what can you say about it i can only regret the fact that i didn't get the English version and i can't exactly say anything about the voice acting since my Japanese is a little bit rusty. But nevertheless the sounds and soundtrack of the movie are brilliant and i think a 10 on the sound issue is more than deserved.
All in all i think this movie is a great homage to one of the most popular games of the series and we can only hope that other movies like this will come out in the near future. Who knows maybe we'll even have a version of Final Fantasy X on the big screen. One can only dream.
