Well after years of watching Tos on Netflix , I welcomed back true trek and ripped my blu Rays onto my plex server , the non remastered versions, in all thier 2.0 glory (wish the original mono was included) still these are the versions that really bring trek home to this 53 year old. And it makes me sad that new generations will prob be exposed to this version. The effects set the mood of the show. They are fine
