Kat's whole arm is robotic, meaning it has to link to her central nervous system. It's either controlled by electrical impulses by her brain to a receiver between her body and the suit, or, less likely, connected directly to her nerves. Either way, all you need is two arms, two legs, and a smart AI could handle the rest.

It's not so much a plot hole, and I don't hold any ill will towards it. If the technology exists for a fully-functioning prosthetic arm, then it would be easier to re-attach a deceased individual's arm. It's been done today with hands, though I don't believe complete function usually returns to the patient.

Yes, to produce a singular, unique AI. But last I checked, the process of copy and pasting wasn't all that difficult.

Find me the part where the Spartan IIIs show up. I think I missed that bit. Not to be snotty, but I'm just illustrating how a lot of this stuff is put in on more of a "cool factor", rather than in the idea of reputable science fiction.

Like I said before, I don't have a problem with it. I'm just a little disappointed that nobody on the editing team asked these questions. Again, "cool factor".
