There isn't enough time to grow attached to the characters. I believe this is more of a fault from Netflix, rather than the writers. Netflix bought too few episodes so the writers had to work around it. Towards the end of the season, our MC says "we're family" to his fellow pilots and while it was a sweet moment, it felt kind of unearned. Why? Because we've barely seen these characters properly interact. In one episode, our MC gets his Robo and one of the pilots is like "he hasn't earned it like the rest of us" and she clearly holds some sort of resentment. By the next episode, they're all chill with each other. This show should be like...twice as long. I enjoyed the cute character interactions but there were too few so their bonds don't feel fully developed. The dynamics between characters who've already known each other is smart and enjoyable but between new ones, that could use work. Aside from that relatively small criticism, I really like the story and animation. The character and monster designs are very aesthetically pleasing and perfectly fit this story. It took an episode before i liked the Robo designs and they steadily grew on me throughout. I think the crew involved has done a good job so i'm excited for the next season. The concepts and execution are done well for the most part so i'd suggest this.
