As a who and trek fan, if you go for classic who I suggest starting with either 3’s era (s7-11) or 4’s era (s12-18), with a bigger emphasis on 4 because his stories are more bite sized (4-6 22 minutes episodes each serial) and then continuing until you finish 7 or watch 8’s movie before going back to watch 1, 2 and 3. 3’s era imo is best viewed after having a feel for what the series is normally like. (3’s era’s initial gimmick is that he’s stuck on earth. And I don’t mean like there’s just a lot of stories that take place on earth, I mean the TARDIS is busted and he’s stuck in the early 1970s.)

ty for the recommendations!! i appreciate it n ill keep it in mind – but jsyk don't count on me getting into it anytime soon haha i said id watch star trek for probably about a decade and only just watched tos all the way through a few months ago...... and ive still got so much star trek left and my attention is hard to divide between things lmao
