wait...Uta was an H-game like Fate/Stay Night originally?

I'm in the process of working through this anime, and I'm loving it.
Its very similar to Azumanga Daioh, although not as random, from what I've seen (I'm ~5 episodes into it)

I like thrillers, but Paranoia Agent just didnt do it for me,
I would have given it a 6 or 7, but thats just my opinion

I loved this anime, I actually watched it twice in a row,
this is a good review, although I would have rated it higher because I liked the OST a lot,

also, a second season has been announced (http://www.animenewsnetwork.com/article.php?id=6427), it is called Rozen Maiden ~Träumend~,
and if you know Japanese, the 2nd Season's official website can be found here: http://www.tbs.co.jp/rozen-maiden/

yea, this is an obviously biased review, I havent seen the anime, but the manga isnt too bad
(you cant go wrong with someone being lit on fire in the bizarre way that someone is in the 1st volume)
the manga's story is way different from what you presented as well, so read it instead

I agree completly with this review, Elfen Lied has gone down as one of my favorite new series,
the ending makes you think theres more to come though (or I'm just way too hopeful)
