It's not checkers, Kampstein....it's chess. Stop moving your pieces all over the board!
Listen, the examples I used are absurd on purpose. My point is, and was, you can only stray so far from an established concept before it ceases to be that concept by any substance or stretch. Throwing Keanu Reeves in all black, and calling him Constantine, does not a Hellblazer movie make.
Again, I am perfectly open to checking this movie out, and being thrilled with the updates. The originals were silly, in retrospect. However, there needs to be something of the definite article there for it to be the Transformers.
And, as for any realism, and all that, CGI can work all magics equally. If they wanted to go with actual Prime look, and have the wheels deflate and slide inside his ass everytime he transforms, then, it could be done very easily. My greatest fear is that they are going so realistic as to ignore the "fun" of it all.
