The film, by the way, is very good. The plot is a bit holey, particularly with regard to the science (I don't expect the science in a science fiction film to be realistic, but it should at least be internally consistent), and a couple of the characters are barely developed at all then thrown away just as you're getting to know them. In particular, I couldn't help but notice how cutesily heterosexual everyone seems to be. But the CGI and the music are both excellent, and overall the film does live up to the hype.
One of the questions that random young journo asked jarred in my mind for a long time afterwards, and I've finally realised why. He asked what we thought of the film as entertainment. The word "entertainment" seemed completely wrong for the experience. For me, the only films I think of as entertainment are comedies. I came out of Final Fantasy crying, with a feeling that I now had a better understanding of what it is to be human. That's very different from being entertained.
