To a large extent, television and cinema sci-fi has been taken over by dumb action stories. Also, they like to lavish special effects which are easier and cheaper to do, such as optical effect rayguns and “cyborg vision” displays. Actual alien and robot practical effects beyond really superficial stuff is quite rare. The norm is basically the “Data” approach of somebody who simply acts stiff and stilted but is otherwise a normal human actor. Even the very notion that a “cyborg” must be a partially robotic human is IMO a tedious trope of sci-fi which tends to be less interesting than most other possibilities. For instance, AI-based artificial life or other self-programming / self-replicating machines are still “cybernetic organisms”. Worse, most of these stories don’t have any ideas about the concept, beyond tedious “Pinocchio” rehash.
I liked that Terminator: The Sarah Connor Chronicles looked like another dumb action setpiece, while subverting many of the tropes. It’s intro sequence was perfunctory. I actually liked it more than the movies, as it dealt with more realistic PTSD issues and turned AIs from generic technological bogeys into actual AI characters.
My favorite cyborg series is still Ghost in the Shell: Standalone Complex and GITS: 2nd Gig in that they explored the tech and societal implications far more than anything else I’ve seen, Rather than merely having a mechanical body and/or brain, the GITS universe is aware that this makes people networked and even hackable in ways beyond what many take for granted biologically. Being able to use multiple bodies, copy or split one’s consciousness, back up one’s personality, etc put near the realm of sophistication of more literary sci-fi, such as Charles Platt’s “Silicon Man” or Greg Egan’s “Permutation City”.
