The story is blatantly boring in the beginning. At first it is slow. It constantly gives you side stories, but somewhere along the middle, the story takes a much more rapid pace and starts packing more action into every episode. The finale for this show is really a spectacle and a fitting end to the series. While I would ask for more from this series, Tezuka Osamu is no longer with us and I do not believe there could be a better ending to this show.
Like many of Tezuka Osamu's creations, it has a unique art style compared to other animes.
It leans towards a Disney art style compared to your standard anime art style. The background art is fine. Nothing stands out much, which is good or else it wouldn't be called a background. The ancient statues seem very legit (and some are based on real statues) and so are the temples.
The OST is unique. I mean you don't here "sha-la-la" and "rune-rune-rune" in any other anime OSTs.
The music can really create an atmosphere that contrasts with the the opening.
The main character Sharaku. Is first shown to be super childish and mentally slow. His character design really shows off his dopiness and his stupidity. His other personalty is the exact opposite of him. He is shown to be super clever and a genius. Just imagine pink next to dark purple. There, thats the contrast between the two. Wato is a decent foil to Sharaku. She constantly protects slow Sharaku, but is always toyed by genius Sharaku. She has the most growth in character throughout the story. Sharaku's father also grows a bit, but his growth is basically spoilers so I can't say much.
Some of the supporting cast is pretty endearing. One of them is a monkey girl that shows up later in the story and she really has good character development despite speaking little.
Overall, there is a pretty unique cast in the story. I have yet to see any other anime that has some of the most moving characters.
This show is truly underrated. It's current mediocre score here on this site does not reflect just how endearing this show can be. Yes the animation is somewhat crude and it might look look slightly weird at first, but I really did enjoy the show the more I invested my time into it. Again, the finale is epic and feels for the monkey girl.
