If I had to classify it by genres it would be action, mecha, psychics, sci-fi and space. Now this is a very mixed bag but the elements are presented in such a way that none of it is forced and it all fits together. There is also some decent humor. Lastly it has a very fitting conclusion. However, the twelve episode count is clearly limiting for the creator and this means we do not get to see his best. Development is inevitably rushed at points and the story as a whole cannot reach the heights that it probably could have if the author was
given more to work with.
The art style is similar to the style Satoshi Mizukami uses in his manga and personally I like it a lot. No excessive fan-service, characters are varied in their designs and the settings are nice. While not mind-blowing (cf. Flip Flappers, OPM or Mob Psycho 100) the animation is good and I would give a 8/10 except for the CGI. While the CGI is for the most part quite tolerable and only really seen in the mecha battles, it is the only criticism I have of the show and the reason is that it does not suit the design of one character. To me CGI works well for geometrical shapes but one of the designs is highly organic and this throws you off a little bit. I think if that one design was changed then CGI wouldn't even be an issue. Alternatively they could have changed that design or even hand drawn it.
SOUND & MUSIC 7/10
The voice acting is great, which is almost a given with anime at t this point, and the sound effects are on point. Now the soundtrack isn't one of the soundtracks that you would find yourself buying just to listen to (cf. Ping Pong The Animation or Devilman Crybaby) it is decent and the music fits the scenes well.
The single best part of this show.Satoshi Mizukami doesn't do cliches and there are no simplistic good and bad characters and characters have well reasoned motivations for their actions. The cast is also quite large but not too large and not a single character is tagged on. They all fit in the story very nicely. Once again the episode count is limiting, but this is one area where the creators skills shine through at almost 100 percent. The only reason it doesnt get a perfect ten out of ten is that the story will inevitably impact the characters and as mentioned earlier the story is limited by the episode count
The show is thoroughly enjoyable since it never drags, avoids cliches and finishes off well. Most of all just seeing the character interactions is very enjoyable, and while this is not meant to be the main draw, it does turn out to be the case.
This is the first anime series that Satoshi Mizukami has been a part of. He is best known for three manga, namely
1 Lucifer and the biscuit hammer--> https://myanimelist.net/manga/10552/Hoshi_no_Samidare
2 Sengoku Youko --> https://myanimelist.net/manga/8070/Sengoku_Youko
3 Spirit Circle --> https://myanimelist.net/manga/38071/Spirit_Circle
To be blunt, all three are masterpieces as far as I am concerned and to see him finally get an anime is something I looked forward to as soon as Planet With was announced.
As an author I think he is one of the very best, if not the best, at wrapping up his stories in a satisfying manner and we see this same skill come through with Planet With. In conclusion the anime is a great one cour show that finishes well but ultimately fails to live up to the creators full potential. Here is hoping his other works get a top tier adaptation. No harm in wishing...
