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?
Not a full-on reviewer but Junkball. That guy’s enthusiasm for starship design appeals to a part of me I didn’t know existed, and I wound up watching half of his videos one weekend not long ago.
