I did not have fun watching Nagi no Asukara .
There is a group of people who lives under the sea which leads to conflict with surface dwellers which was interesting but character were too annoying.
Protagonist is kinda annoying.
Actually every character looked pathetic to me, people who can't pull thier weight in though situation that's what each one looked like.
Protagonist was very forceful in regards to romance which makes me empathetic towards the girl.
Animation was top notch . Background sounds were good.
Underwater scene were stunning.
If you ask me to watch it please don't.
Anime was stretched out, every episode each character sulking for thier crush accept Thier feelings which is totally annoying .
In another words there is no romance but a drama series that revolves around accept of romance which is not covered for the entire series.
It's anime original dome wrong.
