Note that I picked up the "B" Cover, which affects my cover rating. The basic one shown in the ComiXology listings would be a 3. Nothing special about it. I do like the design of the "propaganda" homage covers.
What they got right: The age warning, for one. From the way the Reflector robots treat the humans to Hunter's status, it's not going well for "our" side. The story's getting a lot darker, which should tick me off. However, I really can't see any other way to tell it, and the traitor reveal is well done. And at least they wrapped up all the old questions before giving us new ones.
What they got wrong: I am, however, still not found of the darker, more violent stories, so there is that. This is, after all, based on a kids' toy line. However, that's really it. I also don't like Sunstreaker's treatment thus far. It's not something I like watching characters go through, although it's still not as tasteless as Arcee's being made into a forced transsexual by Furman. I also feel for poor Hunter, but at least they make me care about his fate. IDW's Sunstreaker was a jerk before being forced into being a Headmaster, and I find it difficult to feel sorry for him, considering what's happened to Hunter and that I would think Scorponok holds more than enough blame to extend that hatred to the Decepticons.
Recommendation: It's not like I hated The Empire Strikes Back, even though I'm the rare person who doesn't think it was the best of the series. (My choice is Return of the Jedi, because I prefer happy endings.) I'm hoping that All Hail Megatron is the Empire of the new direction and the next series after the Coda story shows the Autobots taking the Earth back, or at least headed in that direction.
