Sure a lot of the time they didn't show the actual gruesomeness, but you have to remember that I watched this when I was like... 10 >.>
I grabbed this straight off
wikipedia:
"The anime broadcast was in 2003 on the Japanese television station Kids Station." <_<;;
"The manga, especially the original Japanese versions, contains gruesome material and images particularly towards its later volumes. Despite the young main characters, cute aliens, and initial look of a shōjo or magical girl series, the story quickly transforms into one filled with very graphic sexual and violent themes. The English-language [1] and German-language [2] versions of the manga have some edited scenes; entire pages of content were removed from the English-language version of the manga."
Why did it have to be so misleading? If it was that bad, why would they broadcast it on a Kid's channel?
But yeah, regardless it all depends on peoples' tastes on anime series. It just so happened to deter
me, but that doesn't mean that other people can't enjoy the series. u_u;
