I was also first hesitant to watch this anime because of its art style(which is somewhat like 3D animated movies)but I tried its first episode and after that I just went on to continue.
"Its has ACTION,element of SUSPENSE and a lot of THRILL, if that's what you like go for it. It's worth your time."
Sound tracks are ok and Character development is fine.
After the anime I am now following the manga because I can't bear the suspense but they release a chapter a month so that's something disheartening.
{Ignore the art style concentrate on the story.
If you like conventional anime art style it might put you off but on the other hand watching it in 3D art style would also be a good experience.}
