This movie has to be the most mind boggling, horrifyingly appalling movie I have ever had the misfortune of sitting through. This is cinematic brain murder and the only credit I can give it is that it is not easily forgotten. Like a McDonald's Double Big Mac it stays with you, making you nauseous, even after it has been consumed and should have gotten out of your system.
There are so many useless/embarrassing scenes/characters in the movie (e.g: Julie White vs Pot Brownies, Humanoid hot chick, Rainn Wilson cameo (why?!), Jetfire, the hyperactive, illiterate, jive talking negrobots (zzzzz...), Autobot Heaven (!!!?!), every scene involving John Turturro, etc) and an endless display of agonizing, loud action scenes that are really very difficult to keep track off. This movie reminds me of 1997's Batman and Robin in that it eclipses what little story there is (although one could argue that in this particular film there is just waaaaaay too much story), foregoes any attempt at the slightest bit of intelligence in favor of flash, gadgets, ridiculous sub plots and corroded attempts at humor. At the end of the most blistering 150 (!!!) minutes I have ever spent in a theater I felt as though I had just sat through the world's longest toy commercial and one of Hollywood's worst ideas.
Note: If you can, stay during the start of the end credits for a scene that means absolutely nothing at all to anyone with a shred of sense. Including a goofy scene that runs like an outtake is perhaps an attempt at crowd control: those who have been taken in by this drivel can stay, mouth still hanging open wide, to find out whatever became of Shia post-attempted robo apocalypse, and those who know what's good for them can file out, thinking of better things they could have spent their money on.
