I'm not sure if I mentioned it or not, but my son (25) told me, some few months ago, that he had only just discovered Star Trek, and was watching them from the very start of 'The Original Series', in the order that they were first broadcast.
Well, I visited him on the Monday before Christmas, and managed to get onto the subject.
He liked TOS, but commented on how dated it seemed, but I pointed out that it was indeed made in the 1960s, and that this was the first time a series had been made that was essentially "A 'wild west' story in space".
Then it was TNG which he had watched it all. He wasn't that impressed with it TBH, and found it was 'mainly beige', and a bit slow, and really showing itself as a product of the late 80s in it's scripts, subject matter and design.
Then I was surprised to hear that he enjoyed DS9 as it had a lot of variety to it's storylines. Not something that ever made an impression on me.
So now he's just getting into Voyager. "I'm at the bit where 7 of 9 has just joined them..." he said.
"I think you'll enjoy this then" I replied.
