given that they're working with standard definition analog videotape from the 70s - granted it was high-end professional stuff, it was still videotape - the amount of detail and quality they're able to pull out of them, while not overdoing it on the HD upscaling, is a masterful tightrope walk that I think they've nailed. (the fringing around edges was I think inherent to the vidicon tubes they were filmed on, and are not, i believe, artifacts of oversharpening)
