I love the approach to this show. I really do. To me, this is Octonauts Above & Beyond, Mira, Royal Detective, and British spy media mixed in a blender. Both of the former two are really great preschool cartoons. And what a masterpiece this show is!
Sam and Kit are really good partners in this show, and maybe that's mostly because their opposing personalities make them a great example of "opposites attract partners." Sam is a germaphobic man who is serious about his tasks, while Kit is a silly free-spirited girl. And I really love how their British accents sound perfect for these characters being detectives/special agents.
The only reason it's a 9/10 instead of a 10/10 is because of the "fact file" song. It's just kind of annoying and hard to hear.
Overall? If this show can combine three really great pieces of media into one masterpiece of media, then this has to be the best show from Silvergate Media so far, and it's only rivaled by SuperKitties, which came out a year after this.
