Gameplay-wise, FFX was one of the best games in the series, no doubt about that. Yes, I liked turn-based combat and summons that actually could be controlled in combat.
Its art direction was creative, original and fascinating.
Its technology was, at the time, pushing the envelope.
But its characters were childish, voice-acting was horrible and the plot has quite a few holes and inconsistencies. The atmosphere conveyed by the world is decent, but the plot unfortunately brings it down.
All in all, it was a good game, and it certainly deserves a remake - however, they have a lot of things to fix in this remake. Final Fantasy games were always successful not because of gameplay innovation or production values alone (others did those to a greater extent), but because of their atmosphere. FFVII's steampunk/dieselpunk aesthetic and dark, apocalyptic mood was what made that game so memorable, and whichever game you might like or dislike, they all have their own, very distinct atmosphere. Just play a single track from the Soundtrack of a FF game you have played, and you will know what I mean.
To me, this strong sense of immersion was much less evident in FFX and those that followed. I can't really explain why that was myself, but maybe the not-too-well-done voice acting hurt my suspension of disbelief. Maybe it was because, by that time, I kind of grew out of JRPGs and began to appreciate western RPGs more for their customizability. In any case, though - if they can fix the immersion issue, the "new" FFX might just be a brilliant game - to me, at least.
