Unfortunately we have to face the fact that the new OT as they call it is a fossilized version and not the real bones from nearly three decades ago or so. What's important though is to preserve the structure of the beast and not add a finger or an extra tooth anywhere just because you feel like it. Lucas would probably rather throw the fossil in the trash and create a digital model of it instead.

Which is fine. But with his digital models come extra teeth and more fingers that were never there and don't look natural on something that wasn't meant to have them.

What this silly analogy is trying to get at is how inconsequential this change is compared to what GL has done to the OT. I think the Pt was a failure. it didn't even explain threepio's leg, and that sort of thing was really all it had on its plate. And it couldn't handle it. F-

Now that might make me a wee bit bias in my definition of what deserves preservation, but truly this Yoda-facelift isn't going to the same degree as han shoots first or many of the other stupid changes so, it gets an ok from me.
