Visually, I load the original video using Avisynth in VirtualDub and adjust the script (actually have a tailor-made function) so that I can switch between the original and downscaled-upscaled video. I zoom in 150-200% and see what happens to the details. Of course, hair and all those very thin details may suffer but it's a question of balance. And my 50" TV's about 3 metres away from where I'm sitting so it'll level things up too.
