Your kidding right??
Bay is not capable of telling a good G1 story.
To begin with, much of the G1 toon wasnt very heavy in the good story department, but they had a good few, which were heavy in characterazation.
Something that Bay cant, or chooses not to, deliver.
In Bay films "characters need not apply".
Bay wouldnt be capable of bringing G1 personalities/motivations to a film.
And the designs??
True, I really didnt like Bays choices, but useing G1 designs would have been just as wrong.
G1 TF's looked "man made", they never looked like an alien race.
