The original “Transformers” from 2007 was a pleasant surprise that was loud and preposterous, but extremely entertaining. The sequels that followed in 2009 and 2011 basically took what made the original so much fun and turned it into spectacles that relied too much on overkill. This latest installment, “Age of Extinction,” had me hoping that director Michael Bay and his filmmaking crew had learned from their mistakes.They haven’t.This time, there’s no Shia LaBeouf driving the franchise.
