Yes, this comic is full of gratuitous violence. It is an exercise in unrestrained id, an opportunity to give the viscious little monster inside us all a pat on the head and take it for an outing.
Full of biting zingers on social normalities and abnormalities, Johnny the Homicidial Maniac chronicles the life and adventures of Nny, a reclusive psycho who blends in disturbingly well with those around him. Nny keeps mostly to himself except for his bloody encounters with idiots, a-holes or both.
Johnny the Homicidal Maniac will neve be for everyone. The frank, tongue-in-cheek treatment of intense violence is only for those with a strong stomach and a cheerfully warped sense of humor. For those who fit that category, its a gem.
I believe that this book is part of the reason that comic books get a bad rap for being overtly violent and obscene anymore...
Not to say that it isn't a great book, now. Take one part Invader Zim (if you haven't watched Zim why are you even here?) one part Kill Bill, and one part just good old-fashioned psychosis, and you have one great comic book, in my opinion.
I highly recommend this for anyone who wants something off the beaten path.
