Im not defending the guy one bit but hasnt anyone read the green lit original Terminator Salvation script? Its a joke, a really bad joke. You have T800's as golf caddies. It was a doomed film from the get go. McG has the gift of gab in a room full of people. It still boggles the mind how he was put behind the most expensive independent movie of all time with a script that was just awful. Love or hate Bale, whether it be his ego or not, T4 would have been a comedy if not for his demands on the script.
I can go on for hours about how wrong TS is due to missing story lines but its a moot point.
