I have noticed a pattern with Hasbro. It seems that they will put effort into their toys if there is a third party attached or if they are licensing from an external company.
If you notice, their Star Wars toys overall have decent finishes and paint jobs because they are using a third party License to produce the toys. If they pee off Lucas, he could push for the franchise to be licensed to another company.
Transformer lines such as Universe and Animated are exclusively Hasbro owned, the toys don't have to be approved by anyone else nor would they disgruntle any of their partners if they cut back in manufacturing costs. That is why I think they are being lazy as hell with these Hasbro owned franchises.
However when it comes to the second Movie line, they will not just be dealing with their own but will be licensing the design of the alt modes from General Motors and other Heavy Weight companies and investors as well as the movie studios. So if they become slack with the finishes and quality, they would be harming their business relations and upsetting their license owner and investors. They will put the extra effort on the Movie toys.
The original movie line was actually pretty good in overall quality despite some questionable molds (Leader Brawl, Starscream) and I believe this is because the Movie line had other companies involved not just Hasbro.
