I’ve been a Treki from the original episode at 7 years old. My friend used to say that I’ll be watching Star Trek at 80 in a rocking chair. I’m not there yet, but I’m rocking away! Anyway, I suggest you start with the original series of 3 seasons. Then move on to The Next Generation which has 8 seasons, I think. After that, watch the current TV series: Star Trek: Discovery (it is riveting). Finally, the newest series on TV is Picard. In my opinion, Enterprise, Deep Space Nine. and the others are not worth your time. Great post!
