I personally think the team dynamic for the Autobots was really well done. I was thinking about how Ironhide was written into the script after fans reacted poorly to Arcee. Arcee could still have been in the film, taking the role of Jazz: she was small, skillful, and no one would bat an eyelid if she got killed, unlike feminists, who'd have objections similiar to Jazz being the "black" robot. That way Jazz could have been saved for a sequel. Likewise, I wonder if Ironhide could have easily been replaced by Grimlock: they could have played up the role of a "devil's advocate" in the team to the extent that he was no longer a friend of Prime, or his age so he's Kup. I also look at Ratchet and feel it could have easily been Wheeljack: Ratchet is my favourite character, but I wonder if his name was just picked on the strength of his role in Marvel and IDW alone. Still, the care and dedication to saving lives is there, unlike the pure eccentricity of Wheeljack. Overall, I guess I really like how the writers molded characters together to make a true team dynamic, rather than throw in many characters as they could. Any more thoughts? In contrast, I don't think Blackout could have been Soundwave, because Blackout feels like a monster on a leash, alongside Bonecrusher and Brawlastator, rather than a spy.
