This is a spectacular series - about relations in a core(?)family, whose members fill almost all existing niches of personalities and characters in human relationships. It is unique that the lead role, this time, is from the perspective of the person who is more introvert and introspective, less self-assured in her own place in the micro-macro-cosmos, concerned character, harassed and needy at the same time for the extrovert, bold, ego-centered, impulsive characters around her - who usually create endless drama. It makes cry, laugh, love, hate, feel empathy or frustrated - but mainly evokes introspect on human relations and our always unique role in them. Each season presents much sincerity, clear and sharp understanding of the writers and producers. Exquisite!
