they already have enough corny sexual references to choke a space bridge so it would be down to more violence and language. i don't think the language is necessary and i don't think that it would mean more robot violence but rather human violence. i mean, prime ripped the fallen's face apart and bumblebee tore ravage's spine out... pretty graphic, but because they're bots, they can show that in a PG-13 film. so do i want to see humans graphically killed or have the bots dropping f-bombs... hmm. i think it would be superfluous... unnecessary. i think a robo-carnage movie with graphic battles where humans and bots get killed would be cool but would still most likely be only PG-13. I don't think it's "awesome" to hear them all say the F word every few seconds and i definitely don't think there should be more nudity... what would be the point of that? mudflap fapping his oil filter to a picture of arcee without her armor on?!?
