First Off...
YOU HAVE NO CLUE what I want. Don't make a claim so. I'm a HUGE Transformers fan, have been one for 18 years. I know more about TF's than anyone I've ever physically met. BUT I don't fear changes made, cause it's an adaptation. If this movie captures the essence of a war fought by two warring factions of sentient robots, with the core TF's being close in personality and characterization to how they've always been, then I can handle that. Characterization, Personality, Ideals, and Goals of the individual TF's is what I'm wanting. NOT Fighting Robots.
I don't only want Giant Robots Fighting...sure that's a part of it, but not the whole of it. I'm sorry, but if Prime is Prime in characterization, leadership abilties, devotional-stance, and overall design...then I don't care if he is a fire truck. If Bumblebee is still the weak, but eager buddy-to-everyone with a heart of gold who tries his best to be as good as the best Autobots, then so what if he's a beat-up junker Camero.
The thing that will win me over is if they make good use of why the changes are made. The changes themselves will rarely bother me. The only ones that really have potential to bother me is what changes could be made to characters personalities, goals, and ideals. Those will be the make or break for me.
I care little about having an actiony popcorn flick with lots of fighting robots. I have stated from day one I want a movie that will make me say "that was a good re-imagination and adaptation of the core elements of Transformers". And only good characterization and care of who the individual TF's are will do that for me, action be damned.
