The only thing I can say is this:
A cartoon, a comic book and toys are something, but a realistic sci-fi live action movie is a COMPLETELY DIFFERENT THING. Did you want this to be a kiddie's movie with kid fantasies rather than a realisticalization of TF?
To achieve that level of realism in a cartoon, you need to change ALOT of things, remove some and replace some others. This did it for me, it did't look like a bunch of legos stuck together, it looked like ALIEN ROBOTS (and not like cheap, human-made robots) for the first time. This is what TF was meant to look like and should've always looked like. Any other design is secondary to real-life.
