If you know me at all, you know I was already a science fiction fan when Star Trek began. (It’s a rare occasion I get in on the ground floor of something.) I adored Kirk and crew. It took some episodes, but I came to love Picard and crew even more. The Trek story still unfolds, but I left that fold around the fifty-year mark. (Or rather, Trek left me.)
More recently (the rebooted) Doctor Who became my favorite SF TV series, but it’s starting to look like it won’t have the staying power that Trek did. I haven’t been as engaged the last many seasons, and the shift to the 13th Doctor hasn’t worked for me.
Currently I’d have to say my favorite SF TV series is The Expanse.
