I agree with you on some points (removing the hackers, slimming the Sector Seven thing, too long, etc), but some of those points are pretty nit picky and strike me as just trying to make it seem like there's more wrong with the movie than you want to admit.
What's wrong with using Hoover Dam? Your details here are overwhelming! Why are you complaining about their use of Quantum Mechanics and Quantum Physics? What's wrong with them saying the "Deepest Trench in the World" instead of the Mariana Trench, which most people won't know the name of, and they'd probably have to say the "deepest trench in the world" regardless. Isn't it true that most American's don't even know where the hell the Middle East is on a globe? While sad, if they didn't put Qatar - The Middle East, a lot of people wouldn't know where they hell it was taking place at.
For the transformers complaints, what's wrong with details? Would you have preferred the blocky style of transforming they used in the cartoons? I thought it looked cool, personally. I'm guessing you didn't see Optimus's mask, which he removed to talk but kept when he fought (I saw this a couple of days ago for a midnight showing, so I might be wrong on this). Complaining about how not all of them had cannons? What's wrong with that? Some people prefer swords over guns. Nothing wrong with that, right?
I'm not trying to be an ass, I'm just honestly curious.
