Furman's books lately have been doing badly partly due to almost ZERO press. Nada. AHM, by comparison, has had a comparatively major push from IDW. I mean, McCarthy was on bloody Today Tonight to flog the book (they must have run out of asians to pick on that week).
For Maximum Dinobots to do those numbers with very little promotion, the knowledge that the outcome will lead elsewhere beyond the author's control, lacking the Revenge of the Fallen branding, and according to you, a lack of respect for his readership
*; suggests that it is doing at least as well as IDW's other Transformers books, or as well as can be expected under the circumstances. However, for AHM to only do a bit better despite more promotion and a more new-reader-friendly format suggests that it is not doing that well and the honeymoon period since issue 1 is over.
*Kinda over the top there, sport.
