It did what it was designed to do

Rating: 8/10 (8 August 2009)

Now, honestly, I don't understand all the gripes critics have with the movie. Yes, it isn't Hollywood's finest, and I damn well agree. It only had a mediocre story line, horrible dialogue, and to be honest some extraneous plot that was simply unnecessary.
But why would you want to watch Transformers? You watch it for the action sequences. You want to see some awesome fight scenes between alien robots. You go into a Michael Bay film expecting nothing but action. In fact, I appreciate the Transformers series for what it is...entertaining action sequences.
As a holistic movie, it's terrible. But Transformers 2 was never meant to be a holistic movie. It's a summer action flick, and it was top grossing because it excelled at what it was supposed to do. Robots, cars, and guns (and Megan Fox for some).
