Before the blogosphere explodes in the age-old argument of which movie is worse, Terminator 3 or Terminator Salvation, let me state for the record that I think both movies are bad. However, Terminator 3 is watchable-bad (with some highly destructive stunts using real honest-to-God vehicles and a pretty well done bleak ending) while Terminator Salvation is an unwatchable mess full of nonsense CGI and a script with two A stories fighting each other for the chance to bore you to death.
That being said, I think Mostow made the right call in deleting the above scene from the final cut. It made me laugh while at the same time caused a sharp, stabbing pain in my brain.
