For a show with such a distinct vibe, it's surprisingly difficult to pin down exactly what it is about The Great that makes it so enjoyable. It's something about the way its over the top absurdity coexists with such recognisable (if often base) impulses and motivations, along with the tart humour it finds at every turn.
All the characters are grotesque with the partial exception of Catherine herself - although, particularly in this second season, the show suggests that her extraordinary will and her determination to impose it on Russia itself has a monstrous element - yet still on some level relatable, and season 2 successfully develops most of its main characters and relationships to make them sympathetic. Plus there are some fun additions, in their own right, for how they illuminate the main players' motivations, and as pot stirrers - particularly the Swedish monarchs and Catherine's mother. Aunt Elizabeth remains maybe the one genuinely somewhat heroic figure.
