I'll preface this by saying I am not familiar with #NathanFielder's work. I never watched "Nathan For You" and "The Curse" intrigues me but I think it's more drama less.. this.
That said I watched Season 1 of "the #rehearsal" last year and have been rescheduled awaiting the next season. Now I'm a couple episodes into Season 2 and constantly blown away.
I constantly find myself going "no, no. That would be be insane!" only for the reveal to hit and he's actually gone 20 times further and nobody's the wiser.
I'm torn if it's all exactly as he presents everything, e.g. if they're lying about what's being shown or what they conducted. However, I think the entire premise relies on the viewer trusting and believing what Nathan, even if that means being a alright unreliable narrator to build the suspense/story. So, if something came out that all the narration was lies, the show would be DOA.
All that said; I'm constantly in awe. If you're all about "brainless entertainment" it's probably not your cup of tea but give it two if three episodes and see in the insanity lures you in.
25% of season 2 is yet to air and I'm starting to suspect that he has secretly built an entire 1:1 clone of #Houston's #Hobby airport and nobody has known they've been landing in the wrong place for 20 years and being whisked back to the real one in secret every flight.
Just ignore the weird guy wandering the terminal with his laptop, he's harmless.
