The strange thing for me was when I was comparing and contrasting Joseph Smith, Mohamed, and the main character. The only likable one was fictional. But basically, Smith and Mohamed stumbled upon something that is fictionally represented in the main character as something "snapping" in his brain. If Smith and Mohamed were more crazy than opportunist they still come across as less likable.
I would love to "spoil" this show for you - I just watched it last night - but I won't.
