Travelers is good fun! I also came here to comment on the tangential sci-fi discussion, specifically to defend The Expanse. It’s based on a book series and the detective character, Miller, is not supposed to be cool; he’s actually quite depressed and pathetic and that’s the point. The “cool” porkpie hat is used quite intentionally by the authors to show that he’s outmoded and trope-like. The show has gone a bit grittier with the character and that’s fine too, but he’s a quite enjoyable in the book because he’s a throwback character.
