If they remaster TAS, the original doesn't disappear from my shelf. It still exists. As far as the quality of TOS-R goes, it was indeed a very hit-or-miss project. But I'm still happy they gave it a try. Because, once again, my DVD's didn't disappear from my entertainment shelf. Same thing goes for Star Trek 2009
, not exactly my favorite ST property but it didn't erase what came before from the universe.
And I never bought the "disrespects the work" angle. It's a forty year old property, if anything it shows an incredible amount of respect that someone wants to take the time to update it for modern audiences.
