The best thing about The Rehearsal—Nathan Fielder's elaborate Russian doll of social experiments and self-examination—is how seamlessly it goes from prank comedy to surrealist horror. The show's concept of staging situations where real people can practice making an important decision (complete with actors playing all the background characters) pays off in spades. Fielder's insistence on over-preparation collides beautifully with the unpredictability of human behavior, leading to some of the funniest and weirdest interactions to grace TV.
But the greatest trick that The Rehearsal has up its sleeve is Fielder, playing a version of himself using this show to understand how to live a meaningful life. As he stretches these rehearsals beyond their limit (at certain points, recreating his own rehearsals with someone playing himself), his character's persona also begins to crack. Suddenly the series isn't just a comedy, but a poignant reflection on empathy and forgiveness, and a psychological mind-bender about an egomaniac who refuses to give up control of reality itself. There's nothing else like it on television.
