I have all three seasons of the original series with ORIGINAL effects. I DESPISE the "remastered" . I have the set that was released about 25 years ago, in the Yellow (1st season) Blue (2nd season) and Red (3rd) cases. Unlike when I first got them off Ebay 2 years ago, I'm not watching from first episode to last. Just randomly. Yesterday, I watched "All Our Yesterdays" where they beam aboard the USAF Pilot and then "Court Martial", where Kirk is tried for something he did not do that SUPPOSEDLY killed a crew member.
