Both are orphans (assumed though not canonically confirmed for Alison) who live for their found families. Strong but unwilling leaders, far too aware of how the world works. Mum friendTM, hot messes, can and will look after you you have no choice. Also its by the old Horrible Histories cast. I 110% reccomend watching this show, especially as an emotional pick-me-up because it's main vibe is positivity.
There's LGBT rep in a WW2 Captain, British humour, himbos, dad friends, trouserless politicians, a space obsessed caveman, a woman burnt for being a witch, a horny Edwardian lady, plague ghosts that offer you milk, and a decapitated head that WILL lecture you on being a homophobe. It's a sitcom about woman who can see the Ghosts in her house and the subsequent chaos. Preface: Ghosts is an amazing, funny, emotional show with incredible actors and incredible plots.
