I'd safely say the generation one 1986 movie was far superior than the micheal bay TF Movies.
Personally,I felt the 1986 TF Movie had better written dialogue,better story arcs,better robot designs. more 3-d personas. less annoying humans. most important the 1986 movie was from a robots point of view & not from a humans point of view. the intended viewer age level for the 1986 TF Movie felt like it was for older teenagers & adults. the back ground music was awesome. for the most part they had a talented cast of writters,voice actors & animators.
I think the micheal bay TF movies were awful. because #1,the dialogue was horrible,it felt like something spoken from 6o years ago. another failure was the all ages theme,it's never a good thing to mix toddler comedy with serious violence,the end result is always cheesy. i felt like 90%+ of the human cast was the most talentless & annoying i've ever had the dis-pleasure of seeing. having the humans get more screen time & more speaking lines than the robots was another failure in my book. shia le bouf didn't deserve to be in these TF movies,he ruined all the scenes he was in because he can't act out emotions properly,he either under acts or over acts in the wrong scenes. 90% of the robots didn't even receive 1D persona's. while the CGI Robots designs were cutting edge advanced they were still ugly. at the very least the 1986 TF Movies had better robots designs that were more beautiful to see.
