i dont know bay personally, nor did i watch any of the transformers movies after the first instalment, but seriously fans need to chill. if this ruins your childhood then your childhood must have been fragile in the first place--dont blame bay, blame bad parenting.
like comic book heroes come from all different types of universes and shit; the batman with clooney and arnold was shit but it definitely didnt ruin the batman as a character, much like how this movie might be garbage but it wont ruin the teenage mutant ninja turtles that we love.
did you people see the dragon ball z live action movie? that shit was the worst, but it never dampered my love and affection for goku and the rest of the z fighters.
