I have mixed feelings on this one...
....I wonder how they could of done that instead of making a movie. Hehehhehe *HINT*
Anyways, the movie is interesting enough but to be blunt, I would of rather them have made a game sequal. Since it's a movie and has to last about 1 and a half hours it doesn't really seem like much is going on.
In short I'm pretty sure if they made a game with this exact story and good gameplay and it would of been a successful sequal and awesome game.
But I guess not.
Technically Spirits Within was better than this because it didn't make me feel unsatisfied. And I actually liked Spirits Within anyways, it just wasn't very final fantasy-ish. But it was still a good movie and it was deep. Anyways watch this if you liked FF7 but be warned you'll feel empty afterwards =P.
