As a young fan of sci-fi, horror, and action films, I used to bristle when a critic would say some movie I enjoyed was "un-reviewable," impervious to rational analysis, and bound to be a hit with the people who wanted to go see it no matter what professional reviewers said. I thought it was a condescending attitude at the time, but now I've got to throw in the towel on the "Transformers" series. Either I grew up, these movies got too infantile, or more likely some combination of the two. I've heard it said that most big-budget cinema is pitched at 14-year-old boys. This movie was evidently written by 14-year-old boys. Heavily caffeinated ones, at that.
Suffice it to say that "Age of Extinction" offers more of the series' signature sweet cars, hot chicks, silly comedy, and giant robot battles, except this time some of the robots are neither Autobot or Decepticon - the former hunted almost to extinction by their former human allies in a dark reversal of the third movie's upbeat "we're all in this together" ending, the latter apparently pretty much out of business these days - and some of the really big, ancient bots transform into dinosaurs, because it turns out the Transformers and their enigmatic creators were here 65 million years ago and wiped out the dinosaurs. Far from serving as a random hiding place for the Transformers' power source as we were told at the beginning of the first movie, it turns out they've been visiting Earth frequently since before there were mammals. Which makes it kind of weird that it took them almost a hundred years to figure out that their vital power source, and the Decepticons' leader, were buried in the polar ice.
