The Expanse is one I find especially interesting because a lot of the work that goes into is in modelling 3D space ships and other space objects, which I also have to do for the game I'm working on, plus in a near future imaginary universe like that where you can't just bullshit most of the Physics side under the cover of "it's too advanced for our understanding" like in, for example, Star Trek, even the ship design has to follow some actual Engineering and Physics rules to be believable (rocket exhausts point back so ships have to flip to break, guns have to actually unfold and turn to the enemy, the ships have to actually have airlocks, interior storage systems AND even crew sitting have to take in account that the ship will be accelerating, decelerating and maneuvering with high G-forces, taking in account the actual absence of gravity when not under acceleration and so on) and I have a background in both Engineering and Physics so this kind of stuff really stands out for me.

Sure, a lot of things in there can still be bullshitted (such as ignoring the rules of mechanical engineering when it comes to resisting certain mechanical stresses and not really having the kind of design elements that are often present in vehicles to facilitate their construction rather than related to their use) plus as usual the computer UIs are bollocks, but none the less it's a massive and impressive job.
