There's a review of the movie floating around on the Internet of Transformers 1, and it has my feelings about the movie pretty much summed up (I'm paraphrasing)
"If you find yourself being bothered by some plot hole, coincidence, or piece of weak writing, ask yourself this simple question: Did it happen before or after GIANT FUCKING ROBOTS FROM OUTER SPACE CAME TO EARTH TO BEAT THE SHIT OUT OF EACH OTHER? Because if you're willing to accept one but not the other, you're kind of missing the point"
