Re: Transformers 4 is going to be AWESOME.
The point was that Avatar was about humans. As all live action films are. The same way TF is about a boy and his car and his story from that into manhood and self assertion.
As for the development of Optimus and Bee, like cap they don't arc, they just face obstacles.
As for the comedy relief, TF has characters that do that just as Disney movies do. Only with TF fans didn't sign up for it.
As for offensive jokes, when's the last time groups of people walked out of the hang over feeling offended. It is what it is, comedy. It's not for everyone.
Queen Latifah for Amanda Waller the most obvious casting in cbm history
