The latest Transformer movie made somewhere around the amount of 700 million dollars so far. So there’s a good chance that no matter what else happens, there is going to be a part 3.
So I think that what Michael Bay should do for the next installment is hire Dan Brown to write it. When you hear my reasons you will probably agree that he is a natural fit.
You see, the alien robots from the transformers have been on the Earth longer than the human race has, which was either millions of years ago, or 6,000 depending on where you went to school. This is why some of them transform into dinosaurs.
