Before I say this, I just want to point out that I know it's impossible to do. I just want to see if this bugs anyone else as much as it bugs me.

Having said that, I'd very much like to see C-3PO's "stomach" wiring be made consistent throughout all 3 films. It's not such a dramatic change from ANH to ESB, but then in ROTJ it's suddenly gold and silver straight lines as opposed to actual wires. WTF? That's something that bothered me when I first saw the movies when I was 6. I could never understand why they'd make such a dramatic change. That was before I knew of several other changes that had been made throughout the trilogy, though, like Vader's suit and lightsaber hilt. It still doesn't make any of those changes make sense to me.
