I have a few, my fav is Jessie Gender, who gives insightful reviews but doesnt shy away from criticism of Trek. I also like how she looks at things from a gender critical angle, which is something few peoppe think about. Sean Ferrick is another cool one, as are the guys from Trekyards who are more focussed on tech and ships. Who else should I look up on?
Rowan J Coleman’s Star Trek Retrospective series is superb and is what made his YouTube channel famous. He has now branched to other SciFi movies too which are equally interesting.
It’s unfortunate that he said that he won’t have in depth retrospectives about new Trek series but hopefully he’ll change his minds when series like Discovery will end.
