Hidan no Aria

So, this is definitely not based in reality. The show was actually pretty good until about halfway through when they decided to add a supernatural touch in in a very half asked way (think someone being able to control their hair), and probably only to tie in the monster at the end. I did really like Kinji's character and quirk though, he's one of only a few reasons I liked the show. Only 3 of the 5 female characters were even likeable, and 2 of them were villains while the other was just a side character not in the harem.

If they had left out the supernatural entity to this show, they really could have done a lot with it. The main disappointment was that they didn't.

Oh, and never watch the spin off with Aria as the actual main character, that thing is just a crime against humanity.
