Overall a pretty good show, me and my mum enjoyed watching it. I like the characters, but I think Klaus was honestly the best character. He was very lively and interesting, with a developed story and clear contention.
I think that there should have been a bit more action. It is a show about superheroes! I wanted a bit more superhero stuff, specifically some more stuff about the work they did when they were children. It was enjoyable to watch but fundamentally there are definitely some things that could've been fleshed out more. :/
