Sure there's a lot of cut-scenes, but the gameplay far outweighs it. Besides, FF games, at least X, have consistently had some of the most engrossing stories. I didn't say best, but they really get you into it- Square's one of the only companies that realize this. I don't want a RPG that's just a collection of crappy puzzle-dungeons and some random battles thrown in- I play RPG's for the STORY that they tell and Square is one of the best story tellers around. I'm also an avid RPG player and FFX is easily one of my favorites. Not quite as good as Chrono Cross (I'd like to see you try to find many faults in that) and not in the same league as Earthbound, Chrono Trigger, or Grandia 2, but it IS an extremely fun RPG. The "too many movies" ploy is just a sound-bite that people squack back whenever they detect someone who doesn't agree with their view of Square.
As for Kingdom Hearts, it's INCREDIBLY good- not your most traditional RPG, which is good, and it handles the Disney license perfectly. One of my favorite PS2 games.
