Just watched the anime and took about a week to finish it. Was kind of disappointed...
[SPOILER]
I was really annoyed that although she was so fucked up, Yuki still fell in love with Yuno (it's unexplained... at first he's like "I'll just use her" but three episodes later he is actually in love with her)
Yuki out of nowhere becomes this badass with no problem using and killing everyone where for the first 15+ episodes he cries as soon as someone looks at him funny. There was no development of that at all and it was pretty ridiculous.
[/SPOILER]
All in all the show was alright, I really liked the action and loved some of the characters. It really fell off in the middle, though, but was pretty redeemed by the end. I would recommend it but definitely not my favorite anime I've seen thus far
