Sankarea is an anime full of potential.
However, they did not exploit that potential in the ANIME, I've heard that the manga is much better (gonna check that later).
It is lacking in some aspects, but still enjoyable.
First 3 episodes are kinda slow. It is a very light story without any heavy, mind-blowing or amazing plot. Maybe the director could've make it a little bit faster? Some episodes just seemed like sllice of life-type of episodes. It worried me, because this was a 12 episode anime and the director made the pace as if it were a 24 episodes anime, which usually has a slower
plot. The thing is that the climax in the last episodes did not give much of an impact and the romance is still kinda underdeveloped.
I liked the art. I liked how the characters were made and some scenes. However, I do not think there was much variety or scenes that made a big impact. Of course, I know that this anime doesn't have the same budget as Fate/Stay and other big budget-animes. So, for the art, I guess it's good.ç
We do not see them struggle that much. Rea has some problems with her father, but they did not go too deep. They could've made it so much better.
Furuya doesn't develop much. Rest of the characters are pretty 2-D/dull.
It was good. The sounds were okay for the setting.
I liked it and enjoyed it. I reccommend you to watch if you have the time. Still, what disappoints me is that it could've been SO much better. I think I'm gonna read the manga after all.
