Original series still my favorite, since I watched it when it first came out (am I dating myself?). I have seen every episode of all the Star Trek series at least once (except the new ones on CBS pay, have seen the first two seasons of Discovery though, checked out at library.) And all the movies, at least once. I have every episode of all the series on my Tivos. Been so long I can probably watch as "new". Except maybe original series, that one remember most everything, at least after a bit of a reminder. Deep Space Nine, was a bit boring for me at first. But in later years a bit more action, not all political. I have the entire Next Gen series on VHS tapes. Anyone interested?
