-too many explosions (almost every scene had one in some form)

-Weak characters (didn't know most of the characters names, especially the autobots, except Hound, Bumblebee, and Optimus)

-Galvatron's character was dumb. I mean, it had potential to be so much better, but it just seemed like what they did to Rhino in ASM 2

-Movie could have ended multiple times, instead forced to endure 3 hr story

-misrepresentation of the dinobots (didn't even say their names)

-if people in chicago remember, the autobots helped them stay alive during the battle of chicago.... so not one person speaks up asking where the autobots are. We are just supposed to assume either the CIA killed every last person in chicago after the war, or that no one really cared who saved their lives. (okay, their was one person)

-the transforming scenes were dumb; we never really saw a single transformation. They'd start in a car mode, the camera would pan away, sound will play sound indicating they transformed and then we would pan back and they were transformed. The whole "transformium" thing was kind of dumb too. Took away from the whole concept of "transforming"

Things I liked about the movie
-Stanley Tucci
-John Dimaggio and John Goodman's voice overs.
-I did like some of the action sequences
-Some of the jokes were quite funny this go around (not all, but some) Their were a few references as well; Yaeger / Jaeger, the big lebowski reference, and a few others
