Don't forget old was once new Trek and people didn't like it back then.
I've met people who watched The Original Series as teenagers in the 60s, loved it and never wanted to watch anything else again and say they will never watch any of the new stuff.
Personally I love it all ... warts and all.
There is just so much now and it's not easy to find the time to see it all.
My dream now is to see all of DS9 from beginning to end. I've only ever seen a handful of episodes in random order never from beginning to end.
