When people think of the classic Terminator movies; they think of Arnold Schwarzenegger. Should he not be involved in Terminator 4, it won't be the same as before.
Which should be seen as a good thing. Schwarzenegger is a terrible actor.
Serapy hit the nail on the head. Arnold shouldn't be in Terminator 4 because he is a great actor but because of the principle.
I'm not saying Arnold is a great actor by any means but he pulled off the T-100 flawlessly in the first two films so I don't know why you wouldn't want him in Terminator 4.
I think you just voided your validity of opinion for this thread, Dreddz.
