There are no surprises anymore. Not here, anyway. “Transformers: Dark of the Moon” returns us to the Autobots and the Decepticons as they battle it out to save planet Earth. Megatron (Hugo Weaving) thankfully isn’t the sole antagonist this time but that hardly makes things what the suits call “interesting”. Shia LaBouef is back as Sam Witwicky, the focus of the film despite his inescapable irrelevancy. I suppose I should say something like “I loved the special effects!”. I also love tea, but God forbid you serve without milk.
