Mad Science

i09 has a very interesting article that explores the familiar sci-fi theme where "mad scientists" will, one way or another, turn against their creations. Along with characters like Victor Frankenstein and Tony Stark, Astro Boy's father Dr. Tenma makes the list with a very cool writeup. Here's what they had to say:

In the underrated 2009 film, Dr. Tenma turns against his creation, Astro Boy — but later has a second change of heart. Dr. Tenma creates Astro Boy as a robot duplicate of his dead son. But when he realizes that the robot copy can never replace the flesh-and-blood boy, he rejects the kid. (In the original Tezuka manga, Tenma rejects the boy when he realizes the boy can never grow up, and sells him to the circus.) In the movie, Dr. Tenma finally embraces his robot son after Astro Boy sacrifices himself to save everyone from an evil giant robot — and Dr. Tenma manages to bring Astro Boy back to life.
