Smith in the original series would at least cooperate in the interest of his own survival.
This woman they have would rather commit group suicide than keep herself under control.
The original Smith might avoid saving anyone else, but he was never known to get physical with any one (never harm a fly).
The new Smith is a conniving murderer.
Both of them were/are devious.
I really think that changing the ‘script’ is due to the modern audience being catered to. We are no longer entertained by the bumbling clown.
