Finally got to read it (was too busy this weekend to swing by the LCS).
The 2017 FCBD issue is both better and worse than the 2015 FCBD issue; the story progression is much better, with Hakk-R (badass new enemy!) and Fugitoid being brought into the narrative... but worse with the recap.
In 2015, the Turtles have suffered a major loss and are reeling from it. A bit of introspection makes sense there--thinking back over how they got to such a horrible point, what could they have done differently, etc. But 2017... man, that was clunkier than a junkyard.
