I started watching The Original Series reruns when I was a squirt back in the early 70's so I'll always have a soft spot for that show.However,with The Next Generation I was there from start to finish and it became my favorite Trek series.I also really like Deep Space Nine.It might have the best cast overall of any Trek series.I am really enjoying Strange New Worlds.That show is Star Trek done right...it's not serialized and it emphasizes exploration and adventure along with strong characterizations.I also love the references to events and characters from TOS era.I generally like the other series but I could never get into Discovery.It just doesn't feel like Star Trek to me.
