Transformers is as good as it looks*

“Transformers: Revenge of the Fallen” is a horrible experience of unbearable length, briefly punctuated by three or four amusing moments. One of these involves a dog-like robot humping the leg of the heroine. Such are the meager joys. If you want to save yourself the ticket price, go into the kitchen, cue up a male choir singing the music of hell, and get a kid to start banging pots and pans together. Then close your eyes and use your imagination. [...]The plot is incomprehensible. The dialog of the Autobots, Deceptibots and Otherbots is meaningless word flap. Their accents are Brooklyese, British and hip-hop, as befits a race from the distant stars. Their appearance looks like junkyard throw-up. They are dumb as a rock. They share the film with human characters who are much more interesting, and that is very faint praise indeed.
~ Roger Ebert, Chicago Sun-Times
