The show is known for its light and fun tone for viewers of all ages, adults included. Its hero is a science nerd who shows kids that being smart is cool and should be something they strive for. Additionally, Cindy is portrayed as a strong, intelligent young girl who also loves science and is just as capable—if not more so—than those around her.

The show proves that kids’ TV can be innocent enough without compromising a high entertainment value. Kid tested, mother approved.
