I don't mind "do it because we cans" provided they mesh with the original material, and they don't replace the original work. A good part of Star Wars' greatness is due to the visuals, so I have no problem with making them look better, as long as they actually improve the original visuals, mesh with the film, and don't overdo it, in a way that makes the rest of the film pale in comparison. I don't, however, appreciate not having access to the original effects, with the creator pretending that the labouriously created visuals of the original were "incomplete."
