The biggest challenge of "The Rehearsal" season 2 was simply escaping its first season's shadow. Season 1 was a stunning experiment that stretched the boundaries of what a reality TV show was even allowed to be. There were moments in that first season so meta it felt like the show was collapsing in on itself, yet kept going. Moments where it felt like Nathan Fielder was breaking the law, but somehow continued along as a free man. By the end of season 1 we'd gotten an unexpectedly deep look into Fielder's tortured psyche, to the point where it felt we couldn't possibly journey any deeper into him. After watching Fielder spiral into insanity in his attempt to capture the joys of fatherhood, how can he up the ante from there?

The answer is that Nathan Fielder has shifted from tackling parenthood to tackling one of the most high-stakes issues he possibly could: aviation safety.
