From the series:
"Your lives have ended. What you do with your new lives is entirely up to me. That's the theory, anyway."
"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!"
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
