Halo Not Really a Graphic Novel
Despite its name (and price tag) The Halo Graphic Novel doesn't really qualify as such. It's a collection of four short comic book stories, followed by a gallery section of Halo-related pin-up art.
Little connects the four tales, other than the rather thin Halo backstory. What is a gripping, and sometimes even poetic, experience as an FPS video game does not translate well into a comic book, at least as presented here.
