IDW has some great ongoing series as well as a back catalogue of some pretty amazing stuff. One of our contributors for Christmas received several of the Teenage Mutant Ninja Turtles IDW volumes and binge read about 25 graphic novels in the series (they may still be on sale at amazon for $9.99 instead of the usual $50).
For those that loved the Eastman and Laird original run of TMNT you may be excited to learn that Eastman has been involved with the IDW series from its launch. The series is peppered with a large cast some new some returning fan favorites. The stories span time, space, and dimensions while also provided much food for thought.
While the series can be enjoyed as simply narratives about mutants, aliens, ninja, etc. there is a lot of food for thought too. From abusive relationships, to empire building, to exploring ethical questions about life/death, intentions, and motivations there is plenty of stuff to unpack for the interested reader.
