I was thinking to myself recently, and I found out that, for all the concepts, plot points, and character details I could think of in the movies, I could only think of a few that were completely new and hadn't been used before in some form in another Transformers incarnation: - Bumblebee talking through his radio (which I actually liked a lot more than I thought I would) - Sentinel Prime (or any Autobot leader) negotiating with the Decepticons in a way that straight-out screws over Earth - The Autobots explicitly teaming up with the US military. This isn't necessarily a bad thing, as it shows the writers did their research into the history of the brand, and it acted as an opportunity to reimagine previous concepts in a completely new way and improve on them (which, sadly I feel they only managed to do a handful of times). It also may not even be intentional in some cases. I just thought it was interesting that the movieverse is so rooted in the history of the brand (though, I suppose, most series since Beast Machines rely heavily on references to past media). So what I thought would be an interesting thought exercise for us would be to try and think of more completely new aspects to add to the list I posted above, and the more well-versed and wiki-savvy among us and confirm or dispute any precedent to those concepts. I'll also try to add some of the more obscure and interesting concept re-uses, and their originators, I can think of along the way. I'm really not interested in arguing whether or not the re-use of concepts was good or bad in this thread, there's a ton of other "OMG BAY IS WURST" and "MOVEEZ RULZ" threads out there, so let's try and keep it clean, I guess.
