Look, Transformers 3 is a summer blockbuster flick. That is what it is, and what it is meant to be. The implied sexuality is primarily geared towards the young hormonal crowd and the humor - at least from the performers in question - is an established part of their characterizations. The laughs are well-done, and funny as hell! They also don't take up very much of the two and a half hours of the flick, so armchair critics really need to chill out on this matter.
I won't spoil anything further, but I will say that this flick is better than the previous two movies put together. The latter portion of Dark of the Moon is a massive extended battle between Autobots and Decepticons on the streets of the Windy City, so if you've got a grudge against that town, you don't wanna miss this film. Chicago really gets hammered! Returning cast members Shia LaBeouf, Josh Duhamel, Tyrese Gibson and John Turturro all have moments to shine. Frances McDormand, Alan Tudyk and Rosie Huntington-Whiteley are all great additions to the ensemble. Since this IS a Transformers film, the voice cast MUST receive their due with Peter Cullen returning as the voice of Optimus Prime and Hugo Weaving returning as the voice of Megatron, plus Robert Foxworth, Frank Welker, Charlie Adler, Jess Harnell, Tom Kenny, James Remar and Reno Wilson. Leonard Nimoy joins the voice cast as Sentinel Prime, former leader of the Autobots; and genre geeks can expect some peculiar dialogue snippets that homage his famed turn as Mr. Spock in Star Trek.
This is a fun feature film and there really isn't anything wrong with it that's worth complaining about. Recommended!
