I apologize for the relative brevity of this review but there's little I can say without giving away the game. How do you describe the ocean to someone who doesn't know what water is?
I can say this. Clean Room is easily the strongest new horror title to come out of Vertigo Comics in years and it is some of the finest work to date from Gail Simone, Walter Geovani and Quinton Winter. If you haven't been reading it, do yourself a favor and get the back issues. You'll thank me later.
