Review or Die is run by Mathias DeRider, featuring in-depth reviews and opinion pieces on comics (and sometimes more). He has been published in The Don Rosa Classics The Complete Pertwillaby Papers, featuring an interview with the titular comics legend himself. That interview was also used as the basis for a Greek edition of The Pertwillaby Papers.
Other interviews include Jason DeMarco of Adult Swim and Toonami, and George Krstic, creator of Megas XLR.
He also co-writes articles and fiction with K. Tilden Frost.
