Another great one is 'Serial'. It dives deep into one story over the course of a season. For example, in its first season, it explored the case of Adnan Syed, and through detailed interviews and investigations, it told a captivating and complex story that kept listeners hooked from start to finish.
'The Moth' is also excellent. People come on this podcast to share their personal, often very moving, stories. It's all about the art of storytelling in its purest form. There are stories of love, loss, adventure, and so much more, and the storytellers really know how to engage the audience.
