Manga that needs a new anime adaptation

Several anime adaptations have been made out of existing manga, some of them unsuccessful or too short.  What manga would you like to see have a second chance as an anime?

RG Veda- This long fantasy series was only made as 2 episodes.

Outlanders- A short OAV that captured some of the mood of the story, but not enough. 

Dragon Knight- Way too short, loosely based on the RPG series.  Could have used a longer story with more humor, sex, and drama.

 

Gantz: lol, it anything after the Buddha mission needs to be redone, most Gantz fans will agree-
Hellsing could also use an try, only the first half was acceptable IMHO. Needs more villains from the manga.
Blame! the webanime was okay, what could you expect from five minute clips. It caught a tiny bit of the atmosphere, but it would be nice to see the whole story as anime (preferably in black and white)
Battle Angel Alita: Couldn't stand the "movie", but a series true to the manga could be awesome.
