Personally, I liked the plant infestation zombie thing. I keep making things interesting for me in wanting to know just how messed up and different this fictional historical past was like. Plus, the appearance of the plant god quite surprised me. Frankly, I've loved this series from the very beginning, which is quite surprising considering it was a comic that I hadn't heard about until a week before it was released.
I dunno know about that. Image has quite a few lackluster, below average, to god-awful books, it's just no one talks or thinks about them. There's Drumhellar, Genius, Sovereign, Nowhere Men, Dark Engine, Satellite Sam, Undertow, Umbral, and a few others. They are batting the same average as Marvel to me (though light years ahead of Dark Horse, Boom, and Dynamite).
Also, despite quite a few I like, the only book that makes me super excited to read every month is Manifest Destiny. Before I say they take the lead or far ahead of the other publishers from my perspective, they need more than one or two more books to make me feel like that (IDW is even ahead of them in that department).
