I honestly don't like that Zack had to get the buster sword from another dude. Makes the buster sword passing to cloud seem less personal. Would have been nice to see Zack having the buster sword as a family heirloom so that when he dies, it had more value of passing it onto Cloud.
Even the sound effects are worse. Along with the new voices. The old sword spinning sound effect made it actually sound like a large heavy sword was spinning. Now it sounds like someone is just spinning a rope around.
