It doesn't matter WHO does TF4, just the very thought of there even being
a 4th Movie is nuttier than a squirrel turd!!!
We have a trilogy, now it's time to just LEAVE THE FRANCHISE ALONE!! The Fandom is already divided, half of us hated the films, half of us loved them and no matter which camp you are in, history will show that going beyond the trilogy point just makes a film franchise an utter crap-fest. There is absolutely nothing, plot-wise, that can be done that will make a TF fan truly happy unless you resurrect 3/4 of the characters that died in all 3 movies and introduced Unicron on top of it, at which point I will walk out of the theater yelling "What a piece of sh** film, I want my money back!!" at the top of my lungs.
I don't care who heads up the TF4 project, this thing is going to be a freaking train-wreck!!!!
