Original Star Trek was unique upon it's Debut in Fall 1966 because there had Never been anything like it before.
I remember I had done something to piss my father off only a few weeks into that first season. I was punished : NO Star Trek that night!
Determined to see Star Trek that night, I hid under my parent's bed. The Show came on.
It was the one where Spock takes the Enterprise to the home planet of the large brained life forms known as the Talosians. He has taken his former Commanding office, Captain Christopher Pike back to that planet where we see the First Pilot for the show integrated into the new series.
It was AWESOME. I remember saying, " Wow..... " when the phaser cannon was firing at the entrance to the cave where Captain Pike had been kidnapped by the Talosians.
At Episodes ' End, my father leaned over under the bed.
" You enjoy that show?? " He asked me.
" Oh Yes!! " I said, blushing as I came out from under bed..
Years later, I felt the same sense of awe watching the First Alien movie.... and the following summer, when Empire Strikes Back was NEW in theaters..
And a whole army of movies came after that, and now I am really into the Lord of The Rings trilogy..It's Fan Fucking Tastic!
The Point is : The old stuff is COOL....and there will ALWAYS be cool NEW stuff to enjoy, too.
