Until this movie proves me wrong, I'm gonna chalk up Transformers to two words - Michael Bay.
You should - having listened (suffered through?) Bay's commentary for the film, I've said in multiple Transformers threads that pretty much everything that people thought was stupid or out of place was a Bay rewrite. He often says "Oh, I thought that would be funny," or "I heard about an incident like this and had to put it in."
Wait. So some are making an issue out of Kirk saying "man"? Seriously?
Then I guess I must have dreamed that scene in WNMHGB where Gary Mitchell says, "Hey, man, I remember you back at the Academy..."
Thanks for remembering that. I was watching the episode just the other day and that line made me chuckle, thinking of these discussions, but when I came to use it as evidence, I forgot the context.
