Let's talk about this spring anime.
I've seen good series like Midori no Hibi, Shura no Toki, Ragnarok Monster or Tenjou Tenge & even a lot of bad series like Madlax, Kenran Butoh Sai, Bakuretsu Tenshi or Kono Minikuku mo Utsukushii Sekai subbed by a lot of different groups, but till now no one has started subbing GANTZ.

I wonder why?
This is an awesome serie (cause i know the manga & it's great), the design is wonderfull, the animation is good & the story is great. So why there's no group who subs it?
