Pretty much. Its disturbing to see how they trying to make more cash. No matter what.
Without Cameron it doesn't work. The end
This.
They should have had him come back as the guy the machines were modeled after, to battle a second Terminator that Sarah wasn't aware of, yet was chasing her during the events of the first movie simultaneously. Maybe they could have re-shot scenes from the original, where Sarah is being chased by the Terminator, except from the perspective of Arnold and the second Terminator.
How cool would that be if she was totally unaware that there was a second backup Terminator after her, and the only reason she lived is because the guy that they're modeled after narrowly stopped it, and yet received no reward.
