Why have they cut scenes showing T-1000 malfunctions? Except the last one when John recognize that T-1000 morphed into Sarah?
On the Terminator 2 Ultimate Edition DVD there is a featurette called "More Than Meets The Eye" in which director James Cameron explains why the T-1000 glitch scenes were created and why they were absent from the theatrical version of the film:
"The glitching was meant to give some tiny ray of hope that it was possible to destroy this thing, it was possible to affect it in some way. They freeze it, they shatter it, and it reforms and comes after them again, but he's not working quite as well as he used to. I went for the linear thrust and took it out as a kind of embellishment that we didn't really need at that point."
