His role in the first film is superior to his roles in the second and third film where he is a "good guy." His acting in T3 is also a bit off and too robotic. Cameron and Schwarzenegger both mentioned that the Terminator was a smooth machine, but there are some awkward "jerky" movements in T3 that I am not fond of. Towards the end, he starts having non-machine facial expressions and is conveying emotion and such, with half of his skin ripped off. He should just have his generic sullen look, and (OFF TOPIC RANT) his mouth should be ripped in half because it just looks awkward to have this untouched flap of skin that sticks out just so his lips can be in tact. Also, the inside of the mouth. Why is is there? His throat was burned out and roasted. And his machine eye shouldn't be so big. It had to be bigger than his real eye in T1 and T2 becuase it was makeup, but CG could have corrected that problem and instead they just stuck with it.
