The first FF movie is animated very well, but has an average script.
The first "Final Fantasy" movie, based upon the popular video game franchise is visually at the highest level, the computer generated character look very realistic, but it has a script like an average Hollywood blockbuster.
The movie is definitely okay to watch, but the optical look is everything that makes it worth watching.
This movie has some dark scenes, creatures and some violent action scenes. But the movie is not that strong, so it is suitable for children 10 and up.
