From the series:
"Your lives have ended. What you do with your new lives is entirely up to me. That's the theory, anyway."
— Gantz
"Your lives are now over, you bastards. What you do with your new lives is up for me to decide. So there you have it..."
— Gantz (English Dub)
"It's the beginning of a brand new day!"
— Gantz
About the series:
"A tsunami of blood, guts, and stone-cold nihilism make GANTZ the most notorious and controversial anime series of the 21st century."
— Advertising blurb for the series
"R18+: Strong animated violence, Strong animated sex scenes, High level theme, Strong coarse language"
— Australian rating for Gantz DVD box set
"GANTZ is quite possibly the most offensive anime you can get outside of the hentai section. Certainly it's the most transgressive made-for-TV anime to emerge in recent memory..."
— Dan Barry of animeondvd.com, from this review
