After a few delays with the release date this finally arrived yesterday, and I took today to sit down and read through it. This book contains the prologue story, Issue 0.1, and issues 1.0-3.0, which is good for getting a taste of the story and the characters, so if you're wondering about getting excited for the film coming out next year this is worth a read.
I personally loved it, I've been trying to get my hands on the Annihilation series without much luck but this I'm very pleased with. The artwork is brilliant, the writing is excellent, you really get drawn into the world they're creating and the characters you're following. It's also very funny. If I were to compare it to something more widely known it would be TV's Farscape which aired during the 90s, you get a human (well...half human) to relate to, and then a bunch of non-human characters that are extremely like-able, and it's really them vs everybody else. It's exciting, funny, cheesy at times, and absolutely brilliant. Can't wait for the next collection of issues to be released.
