Royal Crackers is funny. It's not the best show ever made but it tries to be good at what it's trying to do. It doesn't try real hard. It doesn't try to less. The show isn't perfect. What Royal Crackers does achieve is to make fun of the way too upper class. The ones that are not welcoming to others.
In between the show is funny with it's small talk. It creates simple comedy by Stebe being the way he just is. Stebe points out things he observes and shares too much. Don't we all once in a while? Maybe the difference is we keep those things to ourselves and don't overshare.
Besides the characters the story is written along a family that has money but clearly does not know how to use it. They have trouble fitting in with the family business and the competitive businesses.
Without spoiling anything from the show I'm going to say you need to watch it. This show is going to be as big as Rick and Morty. It might not be the best and prettiest animation but this show has something that's in the presence of fandom.
Nothing in Royal Crackers is super cringy. It's just clean silly fun. So if you are looking for that cringe like Bob's Burgers offers look somewhere else. This show has stupid comedy. People singing like Korn, People eating drywall, Playing Minecraft. Do not expect them to make a 2 hour movie or get science fictiony on this show. Remember when watching it's just Royal Crackers. It's good but not the best thing ever invented.
