I don't feel that they should do another movie based on the same universe as Final Fantasy (or anything in the past). I agree completely with Zero that an original story should be the possible focus of another movie if they (SquareEnix) were to try again. Completely independent from their franchises. However I did find Spirits Within very enjoyable to watch...I wouldn't say it was a good movie but it was enjoyable.

For the people who found it AC confusing and slow...Advent Children was a movie made SOLELY for fans of the francshise and not as a project that would be produced and distributed for the entire movie going population (that's what Spirits Within was for and it didn't do all that well). ALL aspects of the movie (AC) were based on the prediction that you had played and understood the storyline, characters, and abilities of the characters of Final Fantasy VII.

I also have a question to the people who were complaining about the lack of realism in Advent Children. Firstly it's called "suspension of disbelief".You knew it was a movie based on a video game with the word "Fantasy" in it? I'm pretty sure that if you didn't like the movie due to the lack of realism than you must really not like the game(s). Fireballs coming out of a person's hands, lasers shooting out of swords, huge meteors being stopped by glowing green lights, and talking red dogs aren't exactly within the realm of modern physics either. It surprises me that members of a Union dedicated to the Fans of Final Fantasy are commenting on the realism of anything.
