They had me at "When a Tyrannosaurus...". So, this, was absolutely amazing! It needed no dialogues, sentences, it is wordless, pure and brilliant and I think I am going to read it again, right now. Because, yeah. You could force me to choose in comic book store between any Batman book/Lemire's work/Saga book and Cretaceous, and I would take this without thinking. Twice. Because the dinosaurs.
It was action-packed, dark, gory, heartful, emotional - I cried a little for a few times; refreshing, wonderful, interesting, educational, simply it is definitely a must read if you are fascinated by dinosaurs! The artwork in this is beautifully illustrated. And I'm truly sorry for people who say there is lack of the story. You poor little blind creatures...
