I'm also there with you, that was quite the roller coaster and impacted my trust fairly deeply. Although the totality of the evidence made that one pretty clear to me after researching further than the show; I felt like there was some bad faith cherry-picking going on, which is extremely effective on me but only while it lasts.
A similar series with all the levers cranked to the maximum is "Killer Ratings" on Netflix - just an unbelievable story out of Brazil that left me questioning everything. And that one I couldn't resolve in my head; it still bothers me today.
