I think that despite the amount of bad stuff that can crop up in IDW books there is some really great stuff too. Thundercracker is a character I never gave that much thought to, but what was done with him in AHM and even Costa's run was awesome, I think it took what was originally in his bio and made a fantastic character out of it. Out of all the characters across all of IDWs G1 stuff I think Thundercracker might be by far my favorite. Who else has IDW turned from nothing into someone you now cherish? Or conversely, who have they ruined/wasted?
