k. i have a few questions about the movie franchise. 1) SCALE: starscream is a jet. optimus if a truck. doesn't use the trailer for robot mode. HOW THE HELL ARE THEY THE SAME SIZE!?!?!?!?!?! 2):were did optimus' trailer come from? it popped up in DOTM and i was like wtf? 3) what is the explanation behind bumblebee's design changing every movie? does sam get all bitchy and say " hey im bored lets get you a new car mode"? 4) why is sentinel the ONLY one with a rust cannon? that would've changed a lot. megatron should have had his fusion cannon do that. that would have been awesome. feel free to answer any of these. or ask your own.
