So, that's all well and good, but what does one do when 'errors' are pointed out and then not fixed, or only half fixed, especially the silly, very obvious ones.
I have no doubt all have at least one in mind, but a recent classic was the Galadriel PF. Just about all said how bad the real hair was, so they ended up sculpting it, great, which would have required a fair bit of extra work, right at the end of development for it. But then what happens, the lips are left painted bright ruby red to the point that she almost looks like a street hooker. It wasn't even close to how she looks in the films. Yet how easy would that have been to fix in production, "No, don't use that bright red, use this colour."
The next test will soon be the new Mount Doom SDCC exclusive. The handle on sting is painted all black in the sample pics. Now of course every LOTR fan knows that the handle is not black, but will it be fixed in production?
