I love this show! It's actually quite a personal thing for me, as I am an autistic male, called... Joe! Unlike my fictional counterpart, I was diagnosed at 10, not 5, but this show definitely draws on familiar experiences. With regards the other characters, well, obviously his sister Rebecca is lovely, while her friend is awesome too! Uncle Eddie, played by the amazing Greg McHugh, is a delight, unlike his wife Nicola, who's not the world's most faithful woman. There's also his well-intentioned dad, his aggressive mum, and his more aggressive grandad. We also meet various counsellors, babysitters (again, delightful!) and Rebecca's morally dubious boyfriend, and his odious friend. Definitely give this one a go! You won't regret it! :)
