Thanks for sharing! I hadn't seen that yet. It looks like that guy was telling the truth, Bumblebee's voice does sound like a female!
Well I don't feel I need to go see the movie now XD After seeing all that I'm guessing the movie starts off with Cade and the girl working on Bumblebee and other robotic stuff, when they stumble upon something that signals a Transformer which then tells them something is coming. Anthony Hopkins character shows up explaining Cybertron is coming and that the transformers have been around for ever. Flashbacks tell a tale of how the Transformers have saved the humans and earth a few times, WWII being an example, and then how the knights back in medieval times stopped Quintessa from destroying Earth, to which they must do again. I'm assuming that whole basis has to do with Dragonstorm and how he works for Quintessa, and ends up bringing back megatron to help him. Meanwhile out in space, Optimus ended up being frozen in space and is found by Quintessa, to which is then put under a spell to destroy the remaining autobots and help destroy earth. I bunch of other random fighting that has nothing to do with the plot happens until Cybertron and Optimus show up and the final battle happens. Knights come back, save the planet, save Optimus and we go on to the Bumblebee movie forgetting any of this ever happened!
