I have actually been reading the manga before getting into the anime, and honestly i prefer the manga. The pacing in the manga just flows better, and the art looks better too. I was slightly disappointed in how much the anime relied on recycled shots and still images. The manga has the educational bubbles that you can read if you want to get an understanding of the biological basis, which I found to be informative while not too intrusive. In the anime, however, the entire story pauses while a narrator reads this bubble, which often wrecks the pacing. I feel the show would have served better to let the narrative point to the science without stopping to fully define all the terms.
The plots and villains of each episode vary from intriguing to old school dumb, like the fact that every villain monologues and is evil for the sake of being evil. Occasionally, the show provides an intriguing narrative and antagonist, such as the episode that deals with cancer cells. The tropes and narrative conveniences reminded me very much of Saturday Morning Cartoons, and despite my criticisms, I often had a smile on my face and felt vaguely nostalgic.
One bright spot in the production in my opinion was the soundtrack. The orchestral music was lush, but also often playful. It may have not have always been used in quite the right moment narratively, but the music itself was well made. Also, the use of traditional Japanese drums to represent the heartbeat was I think a brilliant move. It got my heart pumping!
So yeah, the show isn't really that amazing, but it is fun!
