Matt Goldberg over at Collider had this to say,
"The prequel comic is quite good and I thought the interface for reading it was terrific (you can also download it as a PDF). You should not read it until you see the movie. Aside from somewhat spoiling yourself, the comic won’t make a lot of sense until you’ve seen the flick. Inception presents a complicated world that Nolan sets up cleanly and efficiently, but there are rules and roles you need to know that this comic doesn’t present. However, once you’ve seen the movie, I highly recommend checking it out “The Cobol Job” by clicking over to Yahoo! Movies."Inception hits theaters on July 16th. Look for my review Thursday night.
