^ the crop is slight, and the majority of people never noticed it until comparisons were made directly. It certainly doesn't spoil my enjoyment of the episode at all...
On the one hand, cropping top/bottom for 16:9 treatment is dismissed by many, but on the other hand, cropping a 4:3 frame to an even smaller area, showing even lesser of the original footage, is okay?
I personally would only accept the cropping of the TV overscan area top/bottom, if the image is then widened to 16:10 or even better 16:9. But adding no more information left/right and then even more cropping also left/right is inexcusable.
