Another has a very good history: original and addictive, with a good dose of deaths (I said something obvious because is a anime gore)
His opening is unforgettable, very blurred and with this dark typical feeling in the series.
The animation (is my opinion) I like. It stands out in the part of the deaths.
Another is an anime that it is enjoyed? The response is yes, the plot tangles you up to such a point that you can´t stop to see
