The Spirits Within at least trying to break some new ground, and, for the most part, it does. Of course, the thing that everyone thinks about when they talk about this movie is not the plot, acting, or dialogue, but the graphics. Final Fantasy is completely computerized but tries its best to look as humanly real as possible. The characters have pretty lifelike expressions and amazing detail. Movements are pretty fluid.
Textures are impressive.
However, actors do not need to fear for a lack of jobs. There is still a long way to go before these computerized people will be able to replace real people altogether, as it is quite obvious most of the time that they are fake. No matter how hard the graphic designers tried, and I'm sure they tried very very hard, the characters just do not look realistic. Their facial expressions are not perfect, their movements are not perfect, and their emotions seem forced. Everything is close, but not that close.
