In the G1 version ever Autobot and Decepticon were almost equal height. In the movie they said that all the Decepticons were taller than all the Autobots. Even in the Game they were taller. And yet in the second movie in the forest scene they Optimus and Megatron are the same height and Starscream is shorter than Optimus. would you prefer the Autobots and Decepticons same height or would you prefer the Decepticons bigger than the Autobots? Example: Using Optimus, Starscream and Megatron same height or Megatron and Starscream taller than Optimus?
Megatron and Starscream were still taller than Optimus in the forest battle...they were just hunched over quite a bit for most of it...
I like the TFA relation where the Cons dwarf the Bots. It makes it all the better when the good guys win.
