The first season is a detailed look at the Betty & Barny Hill case, the rise of the alien abduction phenomenon and the role that memory plays in it.
Season 2 starts with the Rendlesham Forest UFO before covering various other famous UFOs and talking about the role of myth and folklore in the UFO realm.
I think he does a good job. Particularly interesting is a number of more open ended interviews that are bonus episodes at the end of the seasons covering folklore, memory, UFOs as religious experiences and even the role of The X Files.
That was a good podcast but Joe Rogan is very gullible and has fallen into the abyss of the UFO bs. He has even mocked Mick West while conducting interviews with the usual suspects pedaling the UFO government conspiracies. i.e. George Knapp, Chris Mellon, blah blah blah.
