Its primary characters are uniquely simple, so simple that they only have one-word names. In contrast to the three main characters, there exists a cast of slightly more complex characters arrayed around the main character that create intrigue and add depth to the story. It's the variations in the art, in these side characters, and in the world around the main character that reflects and creates the character. Thus, the main character is uniquely malleable and interpretive, a boon the contemplative nature that the story takes in answering the overaching question.
The art and music similarly support this theme with differing levels of character design by way of dress, color, and facial detail. In addition to character detail is creative and impactful set design. The anime doesn't get caught up in attempting to create photorealistic background, but instead uses a mix of detail and simplicity to convey desired meanings. At the same time, they don't hold back to create comical situations or beautiful scenes. When there's a need of photorealism, they mix in real photos as background. Overall, the use of such diverse styles doesn't subtract from the consistency of the show's message, but adds to the message and erratic comedy.
Overall, it's an enjoyable ride for teen audiences as well as older audiences. It seeks to comedically answer a question that all of us have struggled with one way or another. By use of wit and spontaneity, it creates an interesting yet focused viewer experience that utilizes most of the 11 episodes effectively to create a story.
