Overall a decent flick. Plenty of Megan, which is always good. Too much side stuff. Now I usually don;t mind some "atmosphere" in a movie to help build the universe, but most of this was just dumb. The "twins" Autobots served no purpose and could have just been removed from the movie with no effect on the plot. John Turturro's character was good, but this sequence with the meat shop had some stuff in it that could have gone away an no one would have noticed.
The CGI is of course amazing, but everything seems too "zoomed in" and it's very difficult to tell who's who and what the heck is going on. It's like every robot needs a floating bubble over their head to help identify who they are.
