Kanata no Astra is about a group of high schoolers who got lost in space. Their goal ended up being to get into their home planet and along the way learned about the history of their planet and why they got sent/lost in space.
In the series they had to overcome many challenges like starvation as well as their relationship with each other. the characters in the show were stereotypical but they still felt like possible humans. I especially like the very up bright stereotypical MC. Sure they were cringe at some times but it was still pretty amazing to watch.
The series sound was good with the art being very outstanding. the characters were well drawn and the world was well plot out.
During the series I had felt a huge sense of boringness and dropped it half way BUT after coming back to it I realize it was due to a sense of loneliness from the whole space scene. This might be my personal taste but could be some unknown element the creators of the anime weren't able to replicate from the manga.
One fault of this show (other than the sense of boringness I felt in the space scenes) got to be the sudden abruptness of comedy occurring in the show. I believe they could have done this better because it removed me from the flow of getting into the show. I found this passible however since most of this comedy was due to the characters, who are high schoolers, which would make sense as they are high schoolers.
I would like to point out before watching this is that they brought up some political/moral (around 2) topics that might anger you if you opposed them. (On the bottom of this review is a disclaimer on the topics).
Overall the show was good(7). If they were to fix the sense of boringness and loneliness the show had, I would have probably rated it a 8 or a 9 so maybe a 8.5.
If you want to watch it I would recommend you being prepared to watch 2 episode filled worth of content because few of their episodes lasted for 40 minutes.
I would like to applaud the creators of the anime and manga for the great job they did.
