Well written and drawn parody
The flash is very succesful parody of the final fantasy series (as in, the jokes are funny). The movie does live nicely on it's own too, although you wont understand the humor, without knowledge on FF.
Personally I found the idea of putting school into FF's frames most hilarious. The flash was well written and the wonderfully drawn graphics didn't fail the movie at any point, but instead gave a great boost to the humor value.
Even though I didn't understand any of the voice acting of the movie (apart from random words), the nicely done acting gave good feeling to the movie. Without the voices there would have definately been something missing from the movie. Sounds on the game were genrally also well picked, although at some points, like just at announcement of pop quiz, I think there could have been better choices.
