While I agree with your main premise that EFX movies usually suck, I must point out that you are blaming entirely the wrong people here. As someone who frequently works with the aforementioned geeks, I can assure you that blaming them for the plot (or lack thereof) of the feature is like blaming the Buffalo Bills' waterboy for the team passing 40+ times in a row on 3rd and short. The geeks just create the EFX that their producers request from them. The people you want to be blaming are the studios for refusing to greenlight anything but EFX-heavy formulaic crap, and most of all the sheepish hordes of filmgoers who keep on buying tickets to go see EFX-heavy formulaic crap. Directors who attempt to distract us from their lack of skill by letting their visual EFX supervisors run hog-wild don't help the matter much either.
