In the wake of 2009's explosion fest that was Transformers: Revenge of the Fallen Michael Bay and company set out to create a movie that had more substance and return to what made the first Transformers so successful. Here is an excerpt from the summation of the review. You can read the rest of the review here.
Michael Bay and Co. strive to redeem themselves here for Revenge of the Fallen. Did they succeed? Mostly. Of course, those who loathe the series won't be convinced no matter what, but that begs the question why they'd even bother to see the third film let alone go in with an open mind. There are pacing problems and pockets of goofy humor in the first part of Act Two that threaten to derail the film, but it wisely course-corrects enough to save itself. Its last hour is the full-on human vs. robot war film that the Terminator series has always promised but never delivered. Transformers: Dark of the Moon may not be a great film, but it is largely great fun. In a summer movie season that's only had a handful of films that have really offered that, it's nice to see the Transformers exit the screen (at least for now) on a high rather than low note.
