What they should do is start from scratch and do the manga justice I mean the manga was epic the fighting, drama, romance not like the embarrassment that's there now it has a lot of potential and I would very much like to see it.
What legalities does something like this entail. I'm sure that you'd have to get consent from the Mangaka, who, after the last cluster **** attempt would probobly be aprehencive at best. Which studio would take this? The manga ended almost 2 years ago and the anime died almost as soon as it started, leaving a foul taste in the mouth of it's viewers (that is, if they went on to read the manga).
I would support this. Especially if they stayed true to the manga. It was the artistic licencing that killed the anime.
