I'm the kind of person that would like to see any Final Fantasy make it to the big screen. But, of course, that probably won't happen, at least for a while.

As far as TSW goes, I liked it as a Sci-Fi type movie, but I thought that it was a big mistake calling it a "Final Fantasy", why not just "The Spirits Within"?
Sometimes a little mistake like a wrong name can be very bad for the movie. I think it would have gotten a lot more people interested without the FF tag, just TSW. People expected Final Fantasy material, and were disapointed. As just TSW, many FF fans would have still seen it just because Square produced it.
meh, oh well, still it had some killer graphics.

Who knows, maybe if Square make a lot of money in the future, they'll give FF movies another and hopefully better shot.
