So any kind of trilogy like this that was written one movie at a time is going to have them and doesn't really detract from my overall enjoyment of the film but I still like to find them and fill in the holes myself. Some may just be from not catching everything as I know I missed a few things that I will catch watching again later, but list out any you can think of. For me: Sentinel had created the Space Bridge technology and made a deal with Megatron. What that deal was I have no idea. Supposedly this all happened thousands of years ago. I am guessing mankind existed as primitives since this would have been after the Primes came to earth to stop the Fallen and we saw humans in that scene but its not like there were billions of us to use as slave labor at that point in time. But would Sentinel have really known anything about Earth? How was his deal with Megs going to rebuild Cybertron? Also since he was Prime, he and Megs could have declared a ceasefire\truce\peace whatever to end the war. But Sentinel was taking the Space Bridge technology off Cybertron to do what? If they just needed resources they could have ravaged any planet. Find Slaves? Humans would be a terrible choice even with billions of them. Cybertron has no air, food, water, and everything is giant size. The whole timing of the Decepticons being on the moon in the 60's getting the space bridge parts doesn't really fit in with Megs being frozen for centuries in Antarctica. Also would they really need a space bridge just to get an Army of Decepticons from the Moon to Earth? They could have invaded and taken over in the 60's pretty easily. Who was setting up this plan from the 60's? Shockwave? The Fallen? Megs made it sound like it was his plan but he was on ice.
