I've enjoyed watching this show ever since it came out. Its premise was interesting and there were elements of mystery, as well as a bunch of funny and interesting characters with distinctive personalities. As the episodes continued, I noticed that the "lore" that was hinted at in the pilot wasn't as fleshed out as the psychological depth of each character. And, to be honest, I really appreciated that decision. An insanely good overall plot can be great, but it's the characters and their storylines that immerse us in the world.
And if you think this show has given everything it has to offer in terms of characterization, you should watch this episode - it does almost the same thing as the sixth episode, fleshing out the characters through dialogue, but without boring the viewer with lengthy discussions. Instead, it provides a good balance of action scenes, jokes, and character development. However, the most significant aspect is the characterization that makes them talk in pairs, how they resolve conflicts (or don't resolve them enough for another episode) and how they reveal their deepest thoughts, finding comfort in one another. What makes it emotional is when some characters can't quite reach that point and sabotage the chance to find happiness, leaving them alone with their own thoughts and struggles. This can be relatable to many people who struggle with attachment issues and fear of speaking their minds. The show ensures that you will feel emotional through its incredible voice acting, animation, and most importantly, well-developed characterization.
So, please give me more of it!
