Alongside Double Dare, Rise of the TMNT, and somewhat Big City Greens, this is one of the best shows that kids' cable has to offer. I know people are turned off by the art-style, but personally I don't really mind it, I think it's adorable. At least the character animation itself is quite smooth.
The show itself is quite laid-back and sweet. It reminds me of something I'd watch on 2000s PBS or Discovery Kids (RIP), but in a good way really. The world of SCI is very rich, as there are many characters and everything talks.
The characters are quite likable. Oscar and Hedgehog are nice-hearted kids. I like that for once, they have a platonic boy-girl friendship instead of them having crushes on each other. That would be very cliche and I'm glad that the team didn't choose that route. This shows kids that you CAN be friends with the opposite sex.
But my favorite character has to be Susie. She is mean, but she is entertaining in a way, and she has a cool accent. To sum it up, SCI is a very decent show and I recommend it if you want to calm down.
