Breathtaking and seamless animation. I'm glad they translated Igarashi Daisuke's art to the big screen pretty well. The art and the soundtrack is absolutely beautiful and I'm also a sucker for animes with the ocean/summer days/ fantasy aesthetic themes (reminded me of the anime Nagi no Asukara). Seeing it on the big screen gave me that same chest expanding feeling whenever I see amazing animation alongside moving soundtracks.

Honestly, the storyline lost me a little bit but I'm not gonna say I wasn't entertained and absorbed. I would still highly recommend for the imagery. Can't wait until it is released in English to rewatch it!

Let me tell you first off, tokyo movie theaters are not cheap!!! $20 for a ticket are you insane?! I'd better be getting my money's worth if I'm paying that much. Like this movie better change my life.

Next I want to let you know that I've never read the source, or heard of this title before watching this movie. So this review is my impression of the movie watching it blind.

It actually started off really great in my opinion. The premise of a boy who was raised in the wild is not something entirely new but still very interesting. And it read more

For those that are curious, this is an animated adaption from the manga with the same name, beautifully illustrated by Igarashi Daisuke. For starters, I think the film was definitely ambitious, but in honesty was all round lacking in a sense that the director could not successfully portray the clarity within the material of the original work.

STORY: (7/10) Five whole volumes of plot, filled with existentialistic concepts combining science fiction and supernatural themes, delicate portrayals of the relationship between the characters and the panoramas of sea life- all of these are condensed into a mere 111 minutes, a little less than two hours. Nevertheless, read more

Not gonna lie I originally posted this review/report in a twitter thread but it's so detailed it deserves to be a review here. Due to this though, it's not in the standard review form.

Report: Children of the Sea (film)

Aaaaaaa I loved the film so so much (non manga reader)

Overall it was a very solid movie (cont. SPOILERS)

Disclaimer: this is all opinion!!! You can disagree!!! You can agree!!!


The story was easy enough to follow but I could tell they'd removed a number of other plotlines in order to fit the main story into a short 110 minutes. read more
