From watching the movie, I realized one thing that wouldn't fit the way it was described. When the Autobots are first introduced and Optimus tells the story of how Captain Witwicky found Megatron, there was something about Megatron. Not a mistake or anything - it was his pose! Optimus said he "crash-landed," so wouldn't Megatron be just sprawled out? To me, he looked more like he was in hand-to-hand combat with something. Besides, why would he be in robot mode in the first place? The Allspark was nowhere near him, so he wouldn't have been in robot form to grab it, unless if he was about to grab it but got frozen while in combat. (The Cube would be "moved shortly after to present-day Hoover Dam.") In my opinion, they could push this for a Beast Wars movie (not necessarily live-action), since the Beast Wars took place on Prehistoric Earth. This idea may not be the best, but it would be a tribute to the Maximals and Predacons as well as bring back some fan-favorites (Waspinator and Rattrap are my favorites). If you have something to say about this scene, say it right here.
