yes, they are 2.5hrs+ long, but IMO at least half of it is chit-chat and irrelevant to the guests knowledge often about fitness/hunting/deer/monkeys. I prefer much more focused podcasts, where the interview has prepared a series of well targeted questions.
I think that he believes that by not researching before the interview, he will be better able to represent and empathize with his viewers, who also won’t have done any research before watching. I’m not sure if this is good interviewing technique, but it certainly gives the interviews their characteristic disorganized feel.
Try some of William F. Buckley's old Firing Line episodes, available on YouTube.
Some of the episodes of JRE with Bill Burr I've watched more than once.
