To me, i'd have to point out there's another movie that had a semi-sentient mecha that had tough decisions to make:
ED-209 from Robo-cop.
In my mind, considering the rag-tag nature of these bandits, it is unlikely that they would have such a high end piece of tech.
I rewatched last night. Most of the camera angles of the walker's "face" were such that the crew wouldn't be seen anyway. But one shot in particular didn't show anyone in there. I'm thoroughly opposed to the idea of a "droid core" for several reasons.
1) The Imperial AT-ST was piloted by direct sight. The "eyes" are windows, not sensors. A droid brain would have required a sensor package, and most likely would have been noticeable.
2) Somebody (I believe it was Cara) shot it in the "eye", tripping it up. It would be highly convenient that a shot like that would have actually
damaged a primary drive system at that angle. More likely it scared the piss out of the pilot who bumped the controls.
3) If this actually was what they did, it's another fine example of Disney regime idiocy and shoehorning in crap to fit a weak narrative while trying way too hard to be edgy. I'm trying to stay positive and like this show.
4) All the toys depict at least one occupant (pilot).
I found it kinda creepy that the widow is that eager to fall in love with him. Unless it was lost in the time lapse. I think he was there for a couple of weeks, but I'm having a hard time braining today.
Also.....What......the......#$%&.......? We're doing mercenaries with cheek cheers now?
