I don't really think it would effect the wider-audience if there was the
Ark story, and
Megatron was a tank,
Ratchet had a white color-scheme,
Starscream be more humanoid on Earth [then animaloid] etc. However the story, look, and feel of the movie that [I'm imagining] we're getting [I say immagining, because I don't know for sure that we're getting, what I think we're getting] is working together with the new designs [including no mass-shift, and
Cbertronian language], character arcs, the
Allspark causing
Transformers to get to Earth well. [It is more believable, than having
Transformers go to Earth for it's resources, there are trillions of other planets full of energy . . . eventhough they didn't exactly choose Earth, and crashlanded on it instead, I know]. I can't imagine the wider-audience believing that advanced robot's such as
Transformers are running out of energy on their home, planet . . . they're so far ahead of us, that their energy makes sense to be virtually limitless in this new, reimagined version.
In short, I think that a Closer G1 adaptation could be a success, but it would have to happen to be one of those cult followings phenomenon. Which I think was a risk the studios wouldn't dare to take.
