It's a solid sci-fi film that was truly a technical achievement for its time. No CGI aiming for realism came anywhere close to looking as good as The Spirits Within when it came out, and it remained that way for years afterward.

I've always felt that what caused its failure is, ironically, the fact that they titled it Final Fantasy. It has nothing in it connecting it to the games, and it's not a fantasy film. Had they given it some other completely unrelated ominous sounding name and marketed the hell out of it outside of video game circles, I have no doubt it would have been a modest success.
