I absolutely miss them original crew. Those that have passed away, that is.
I'll always go back and watch TOS and the original films. I will remember them for as long as I live, and I will miss them in the sense that we will never see another new adventure with them ever again. Those days have passed.
I remember, having watched TMP, and then a lot of TNG, and then finally TOS, I was amazed to discover the other five original cast films. It was great to watch those one at a time in rental/purchases from the store. III, II, IV, V, VI. Each one, better or worse was a great experience. Then, there was no more, and that was sad.
Watching a rerun is like looking at an old photograph. Rewatching TOS is like pulling out the old album. I'm not making new memories, i'm relieving old ones. That is where, and how, you can miss them, even if they are "forever" saved in some medium. I can never be an eight year old in the early 90s watching Space Seed on TV for the first time.
