In our neck of the woods Star Trek is on at 12 noon, so I occasionally join my husband for lunch with Captain Kirk.
We saw all these programs and loved them when they originally aired back in 1966, but I remember none of the details-- just the characters and a few tag lines like "Beam me up Scotty". Watching the reruns is like seeing them for the first time. I have no idea how each episode will unfold. My fellow Trekkie, however, recalls all the details and doesn't mind sharing. "This is where the bad guy from the penal colony arrives." "Here's where Kirk is at the OK Corral".
I enjoy the commentary, and the company. The closest I got to Star Trek while at work was once a year when I turned up in my "Information Officer on the Enterprise" Halloween costume.
