‘Transformers: Dark of the Moon’ 3-D Blu-ray review

If you’ve been holding out for the ultimate edition of “Transformers: Dark of the Moon,” it’s available in a four-disc set that includes a 3-D Blu-ray.

This edition contains more than three hours of bonus content.

“Dark of the Moon” may be the most technically adept of the robot-fighting series, and director Michael Bay has proved himself with this film as one of the directors who has a handle on how to use 3-D filmmaking. If you’re looking for a film to show off your new 3-D television with, this could be a good choice, as the movie starts off with a strong 3-D element. Unfortunately, the plot is labyrinthine, and the film’s ending drags on for too long, overshadowing the strong beginning.

“Transformers: Dark of the Moon,” for the third time, features the conflict between two factions of an alien race of robots, the Transformers, based on the action figure line from Hasbro.

The Autobots, led by Optimus Prime (voiced by Peter Cullen), believe in working with humanity after leaving their home planet of Cybertron; the Decepticons, led by Megatron (voiced by Hugo Weaving), wish to conquer Earth and destroy the Autobots. Bay should be given credit for casting Cullen, who created the voice of Optimus Prime for the 1980s cartoon, and sticking with him for all three blockbuster films.
