In getting ready for the GotG movie I've been reading some Marvel Cosmic. Specifically, Annihilation, Annihilation: Conquest, War of Kings, and I'm on the last book of Realm of Kings. Up next is The Thanos Imperative and then Annihilators. So far, Annihilation was great, A:C was almost as good, War of Kings had moments it could have been really good but then just died and Realm of Kings is just dumb. I hope Thanos Imperitive is better, frankly.
It pissed me off when high-level stuff would happen in one book concurrently with another book but the result would be almost 100% different between the two. Or events would happen in this book and then you'd start reading the next (and I'm reading them in official Marvel order) and those prior events haven't happened yet and you know what's coming.
