I know for a fact that fans are disappointed about one word in each movie... Brother! In the first comic of the movie, in one strip Optimus confront Megatron and says "Hello Brother" and Megatron confronts Optimus and says "Hello Brother". In the first movie when Megatron dies Optimus says "You left me no chose brother". I don't remember them saying they were brothers in the movie game. In the second movie, when Optimus and the Fallen wrestle, the Fallen says, "Die like your Brothers" and Optimus says "They were your Brothers too" Don't tell me that when the third movie comes out, Optimus will call Shockwave his Brother.
