[Ruined]

I think dugpa is right that this is one show where you'd probably get most people complaining about the HD version if they didn't re-do the effects if necessary to get HD quality, especially with the process dugpa mentioned which probably blurred out any additional detail that would have been made possible with a straight up HD transfer of the originals. I guess they could try to emulate the original effects by redoing them from scratch, but why spend all that money when people would likely pay more money for the version with new effects? Plus, emulating the original effects still wouldn't be "authentic" to some ST fans.
