Is "Hell Girl" A "Hell No?"

I've been up for more than 6 hours now watching "Hell Girl," produced by Aniplex & Studio Dean!  While there are aspects of it that remind me of Viz Media's  "Death Note"--a pretty decent anime in my book--there's something about it that's just not capturing my attention completely.  I will say that content and profane language make it unsuitable for children to view.  Some of the characters are repetitive, with little to no change in dialogue.  However, I will refrain from passing final judgment until I've viewed the entire series.  Now, on with the show!!!!!!!!!
