Review of Land of the Lustrous
You might be tired of hearing of the saying "Houseki no Kuni is the gem of this season (pun intended)." And for those who do not understand the pun, let us talk about it, because it really is a gem regardless of which season it was aired. The story plays out as there are only a few what we may refer to as "people" left in their universe. Our characters defend themselves from a different race since it was what they have been doing for as long as they remember. What I can tell you is that there is not much development for the plot, butrather the focus of the development was on our characters. The main character is the "useless one" in their group, and as the story progresses, we will witness the changes s/he has gone through. There might be some aspects that might be confusing, nevertheless, the plot was still all right.
With regard to characters, each and every one of them have their own personality, quirks, duty, effectiveness/usefulness and role in the story. They can be easily recognized (and remembered) due to their individuality and character design. Considering that our characters are actually gems (thus, the pun), their names were also based off on those precious rocks. In a sense, you can say they were well-written. On the other hand, it could make you wonder who the "antagonist" really is. As I have mentioned, the focus of the series was not the resolution of the plot, but the development of the characters. I'll leave that portion of deciding which character(s) is/are the true antagonists. My only objection is that the show claims that our characters are "gender-less," but all of them, because of their character designs, can be easily classified as male or female.
In the art and animation aspect of the series, some might be put-off or discouraged in watching the series, mainly because of the computer-generated imagery (CGI). However, do not fret, as the art and animation was not bad per se. Still, you might have qualms against it due to it not being conventional. It is a bit different, but it isn't worse as I have imagined. Give it a chance after a few episodes, and you can decide then.
In terms of the sound quality, it was fine. I have no complaints. Except for the OK opening and ending songs, and the effective use of the particular background music in the concluding theme, I found nothing else that was noteworthy in particular.
[TL;DR]
Houseki no Kuni was a gem because of the characters, and it was also considered a gem because not many can appreciate this type of show (CGI).
