Sorry but your post is filled with "details that are part of the Transformers DNA" that had not been part of the DNA in a widespread mainstream form back in 2007 outside of anything except the original G1 brand. Arguably not even now, since out of all modern cartoons, only Cyberverse bothered repeating that lore to such accuracy in relation to the old cartoon. Absolutely weak to say "popular excuses" as if those things needed to be excused too, since Transformers has clearly been a healthy franchise for long and long years while making use of that methodology, so clearly it worked and clearly no child ever walked out of the franchise because "They gave the name Perceptor to a character who isn't a scientist or a microscope" or because the robots crashed on Earth in meteor mode instead of inside of a giant starship. And that is not getting into the assumption that characters most recognizable forms would be the G1 versions when we have various G1 characters that have been outclassed in the public's mindshare by newer versions such as Bumblebee himself. You are free to say that your "ultimate transformers movie" is one that echoes your childhood dreams, but everything else is just woefully exaggerated to untrue. It is also weird to talk like the films have been somehow not "setting the basics" when first movie was a basic "Autobots and Decepticons fight on Earth for a powerful object from their alien world" story that various cartoons had already done by this point.
