@billymaysrip: Does Gantz the anime differ much from the manga? Because I thought the manga was a good idea with terrible execution. Just boobs and blood with no substance.
It's been a while since I've watched or read Gantz, but I don't think it differs too much when it comes to the events that they both show. The biggest difference that I can think of is that the manga keeps going long after the story in the anime wraps up.
If you didn't like the manga, I don't think there's too much that you'd feel any differently about in the anime. But again, my memory is a bit fuzzy.
