Untrue. The Spirits Within was an attempt by Square-Enix to create a movie that would be enjoyed by not just fans, but your general movie going public. The majority of the movie going crowd are not gamers. So, this means that creating a movie based on one of the games would mean completely alienating a huge chunk of their demographic. At the same time however, they still wanted to create a movie that their fans would enjoy. Amazingly enough, The Spirits Within has more connections to any FF game, ( especially FFVII, ironically, ) than Advent Children did.
The Asteroid of the destroyed Alien planet.This could be likened to Jenova from VII. Jenova was also carried on a asteroid, much like how the Alien Spirits were carried aboard their Asteroid.
Gaia, Spirit Energy.Can anybody say the Life Stream? Gaia is pretty much the lifeblood of the planet, also damn similiar to FFVII. At the same time, the Military in Spirits Within could be likened to Shinra. They use Spirit Energy as a source of energy and power. Much like how Shinra used the Life Stream to produce Mako.
Zeus CannonSister Ray of FFVII fame. 'nuff said.
Where the shit is Cid?Doctor Sid. Unconvential spelling of the name, but it's exactly the same.
Dude, you lie! Aye Cee was teh bestest ting evaThis is also untrue. Advent Children is a medicore film. The only people who say otherwise are Final Fantasy fanboys. Esspecially the rather annoying hardcore FFVII fans. They enjoyed it because they finallly got to see fan favorite Cloud and gang move around and speak for the first time ever.
Now, don't get me wrong. I did enjoy Advent Children. But that was because it was fanservice. It was made to pander to the fans. On all other fronts, Advent Children was bad to mediocre. You had lackluster voice acting, horrendesly overcomplicated and confusing plot and not to mention obvious money greedy attempts of fanservice.
The Spirits Within however, was new and original. It was still fanservice on some level, but not on the same level as Advent Children was. It featured new characters in a new, more sci-fi enviroment, with an entirely new, but still connected plot.
Now, The Spirits Within was not a great movie, but it's also not a bad film in it's own right. I'd place it in the decent section. But this alone is why Advent Children is an inferior film.
