I'm not. Her elimination the day after shooting began means one of two things:
1. The script will suffer severly from major ongoing rewrites occurring as the film is being shot, or:
2. The script was so bad to begin with that they can eliminate the second most important human character without it making any difference.
Basically, there's no way this can bode well for the film's script. If they'd eliminated her character a year ago it'd be a different story.
Fox was never an important character in either movie. Tell me one thing that her character does that actually drives the plot forward, or plays some sort of important role essential to the plot?
I know she is the "love interest", but really how important was she?
The fact is fox's character never served any purpose what so ever, other than to give the target demographic something to lust over inbetween the action scenes.
Sam and Optimus, Bumblebee and Megatron are the most important characters, if they had got rid of any of those then we'd have something to worry about.
Basically, shes just the token "hot chick" who serves no important purpose to the plot.
Getting rid of her will have no effect what so ever, and adding in a new character to replace her will take all of five seconds to explain since she will be equally as unimportant as fox's character.
You have nothing to worry about my friend. Bay knows how to deliver on the action, and with such a short shooting schedule its a safe bet that we will have more action and robots fighting each other than the last two movies combined.
Might be a little CGI-heavy, but with ILM on board that isnt a bad thing. And with a PROPER script, and no stupid writers strike messing things up we should have a real corker on our hands come june 2011! (or was it july?)
