When I watch TNG-R to me it looks like a cleaned up print of the show as opposed to the faded and muddy look of the original version. I know there are small fixes in it, but I find they don't scream out to me. To me the changes seem small and unobtrusive. This is in real contrast to TOS-R which leaves me exclaiming WTF!!! over and over and over again.
Sorry, didn't yet see you beat me to the punch in stating the obvious above.
