Hm, I didn't see any issue with the fluidity of the animations in battle, even if they are 15 fps. To me, it doesn't feel juddery or anything. In that regard, I usually hate it when they artificially increase the amount of frames in games and movies, as it creates a strange 'soap opera effect' where it seems like the camera is somehow moving along with people's every motion, and it just feels too fluid... probably because fake frames were inserted that didn't exist in the original.
I remember seeing the movie The Hobbit in theaters, and even it (which was natively shot in 45 fps instead of the normal 30 for movies) felt completely... wrong. I remember there was one scene in which it seemed as though Radagast (I think) was moving in a sped-up way, like a tape was being sped up. Still, I wouldn't be against more frames per second if it looked natural enough. Normally that only really matters to me in shooter games revolving around quick response and twitch movements.
The analogue movement missing was definitely a flaw, though I didn't hate it as much as most others. After all, most of the movement in FF8 is kind of focused on tight corners anyway, sometimes even very sharp angles like when moving up the broadcasting station in Timber, or going down to the mayor's house in FH. That said, it was certainly an annoyance.
