Ok so where the hell was Sentinel's destination in the beginning of the movie?? Earth? Earth's moon? Cybertron headquarters? Autobot city? Or Megatron's Palace? Well wherever he was going, he had already made the deal with Megatron....so whos dumb idea was it to shoot down the Ark?? The decepticons? If so why didnt Megatron tell them to stand down if he was Sentinel's partner in all this and needed Sentinel? Wouldnt this jeapordize their plans? Or Megatron didnt care...? And why meet-up on Earth?? for us human workers to help re-build Cybertron?? They could have called a truce then!! Cybertron was totally ruined then!! And back when this happened....Earth, i imagine, didnt have as many humans/workers on it as it does now.....seemed kinda pointless back then to travel so far for so little. Even if they still needed our resources, I imagine there were closer planets with the same or even stronger resources to choose from. And all this time, was the Fallen still in the Ship of noodles in our solar system talking to Megatron via Skype?
