It was really a fun show to watch. I started watching it around ten years old, and I have to admit I thought Penny was super cute lol. Loved how she was the mastermind behind solving crimes. Plus, making the young girl the genius of the show was important because it portrayed a female character as very smart at a young age and probably made the show appealing to young girls as much as it did boys. The second season was not as great. Instead of focusing on schemes to take over the world, Dr. Claw was just hiring people to get rid of Gadget. For three episodes too! And they never got caught either. I liked the episodes where Gadget went into space as well as the time travel episodes and the one where Gadget shrunk.
