Yeah eighties toons are totally preposterous if you think about the finite stuff, but they're all in good fun. And honestly, they explain how she's he's twin from another planet pretty clearly in the introductory cross over movie.
I don't like how Bay takes a good premise and dumbs it down for the hot cars girls and booms. I'm glad First Class didn't go that route the way Green Lantern looks all flash and no substance. I'm tired of flash without merit.
