[Time placement: Transformers: Defiance #1 and Revenge of the Fallen according to the inside cover--I'd actually put it before any of the current comics, since it takes place during the Fallen's final visit to Earth depicted in the second movie.]
What they got right: The origin of the Movieverse Decepticons works about as well as anything that came out of the second movie, so your mileage may vary there. Mowry does a good job of fleshing out (pardon the expression) Jetfire as well as his motivations for both joining and turning against the Fallen.
What they got wrong: I wish I could either compliment or complain about the art, but the coloring is the real villain here. You know how people complain that you can't tell one robot from another in the movie? Well, it's worse here than most of the comics set in the Movieverse and the Movie itself. Not only is there nothing distinguishing the Constructicon drones from each other in robot mode (and barely obvious in vehicle mode), but any of the Primes as well as Jetfire. Thanks to the coloring, I can't tell which limb belonged to a Constructicon (or even which Constructicon) or Jetfire during the fight scene. Baumann may have been the wrong choice for this comic.
Recommendation: If for some reason you were a fan of the movie's story, then this is a good comic. Otherwise, while not the worst Transformers comic I've ever read, the art–or at least the coloring–makes recommending this comic rather difficult.
