I've been thinking, did anyone ever consider actually re-shooting the FX-elements with full-size replicas of the original filming models, using the original film stock etc., only to composit it with modern software? I would LOVE to see the results of such an endeavour. I bet it would look stunning.
Having said that, personally I prefer what little we saw of the work Eden FX had done for the remastering. Looked really like TOS and
was in high definition. I wish they would have been allowed to do the whole project.
