I've heard it's very good as well, and there are many sites about it around. sometimes I had the occasion to check some of them and the style of this series looked good to me. I'm not that rich to get it at the moment, so I cannot really tell you if it's true or not.
Sometimes reading others opinions is not very helpful, because I've watched many series because they told me they were good and then they were not, at least for me
But I also repeat that the style of this series looks really good and the characters are also interesting. But I can't tell you anything more
I suggest you to browse some fan site, that is what I usually do when I have doubts
