I quickly pasted in the original shot (or as close as I could get from TrekCore's SD screencaps. It's a few seconds off) literally upscaled (resized) to match the HD version as closely as possible.
Sure, the original has some VHS fuzz on it, but is it me or is there sharper edges/more "realistic" contrast and overall detail (minus the fuzz of course) than the new HD version?
Most of the other shots can be explained away via preference for matching the original, but why it looks this bad is just incomprehensible to me. :S
