Letting my nine year old write a blurb down below because he'd like to see another season from them. As a parent, with a fairly mature child, I was fine with letting him watch the show. He loves playing the card game with his grandparents and uncles and he was really excited that they were making an animated series.

I love the series, the story and the game I want them to make a season 2 of exploding kittens.
