Art: The art style is unique in a word. Many think if the art bad so is the series, but the art style certainly goes well with the story and does catch the watcher's attention.
Music: The Music for this series was just perfect. Each song went well the tense or funny or sad scene. The song I enjoyed the most would have to be the ending song. After seeing such a good episode leaving us on a cliffhanger or tense scene hearing the ending song would just leave me in awe and give me a hunger for more.
Character: The characters were so well done. All of the characters have a unique personalities that suited their characters very nicely, but the 2 that certainly stand out are Smile and Peco's. Their relationship as hero and robot really made this anime as great as it is.
Overall I found this anime very enjoyable. Many underestimate this anime at first glance due to the art style. But for those who take the chance to watch it and stick to it, you wont regret it.
