Forgot I made this thread... I was very disappointed since they left out over 100 pages of material I would have liked to have seen in the movie. That's not even including any of the ecchi stuff. Also I don't like that they completely removed the Kurono factor, his growth as a human is one of my favorite aspects of Gantz.
I'm going to watch it again whenever someone releases a Japanese language/English sub and see if maybe it was the HORRIBLE and awkward dub that made it so bad.
Funny thing though, I watched it with about 12 people and only 3 of us didn't like it, the 3 that read the manga. All the others only watched the anime.
