Well that's just petty of you to say Possum. Transformers was no more a nerd movie than say Pirates or Spiderman, or really any other summer blockbuster.
Except I liked this more than those film because it actually really caught the feel of the source material. Face it, the Transformers cartoons were always goofy and I was half expecting Bay to turn this movie into a serious and dark epic, thankfully that wasn't the case.
I honestly didn't expect them to shout out their cheesy lines (I don't want a piece of you, I want TWO!) or act like goofs, but they did, and it gave the movie a certain personality that no other action blockbuster in a long time has had.
So call me a nerd for liking the movie, but it was sweet.
