Alright, I finally caught up with the last of my overdue summaries and reviews for the IDW comics I missed. Here they are at TMNT Entity:
TMNT Universe #16
TMNT Universe #17
TMNT Universe #18
I didn't dig "From the Heart, for the Herd" as much as I thought I would, but "Monster Hunt" was great. While I wouldn't want EVERY issue to be drawn in this style, it is a fun break from the norm. I dunno if there's a word for the aesthetic, but I really dig it. It kinda reminds me of David Aja, but better (unpopular opinion time!).
Allor's script was funny, too; he's good at doing both the bigger "epic" sort of stories like Utrom Empire and smaller one-shot comedies like this. I'm glad IDW keeps him on the braintrust with Waltz and Burnham.
