The recent TFMovie designs can be attributed more towards marketing than anything else. It was a no brainer they would change the appearance of the TFs. All it takes is a look back at some of the scrapped concepts for recent comic movies to know this. Transformers obviously has greater marketing potential than any recent comic film because of the toys. Keeping the G1 designs the same would leave little room for marketing. Its a smart business move to change their appearance for this. Everyone is acting like if the blocky-bot models were maintained that the robots would look more G1ish. This is only half true. The blocky-bot models would still be altered in some sort of way to fit the marketing demand so that complaints could still be received from hardcore fans. An example is Armada/Energon etc., which keep the blocky appearance, but are still sometimes hated on by G1 fans. Bay's explanation for the sleeker, sexier look only explains a portion of the character design rant. Regardless of how the bodies look, you can still retain the basic definitive features of the robots. For example, "movie" Prime has chest windows with a "mouthplate" and a G1 shaped helmet, etc. Every TF has a distinct feature that is recognizable for that character, and is capable of being retained despite any alterations in design. If you look at the movie concepts, you will see that the further you get from Prime, the further this principle is lost. This lack of consistency is confusing especially when considering Megatron. At the bottom line, Michael Bay, who originally dismissed the project, is more into the film because of the Box Office potential instead of being a fan himself. This could result in a failure to recognize why fans feel a connection to the TFs. Films like LotR would have been horrendously thrashed if Peter Jackson had a similar outlook. If the director is not a fan, it will show in the film. Michael Bay's lack of attention to detail might have little effect on the masses, but could lead big fans like myself to download the film for free instead of hitting the theater on release day.
