The Mole: Undercover in North Korea

Not too bad but unsure how realistic it is. Creators could've made attempt to contact authorities to confirm that it was real. Otherwise it all sounds too ridiculous. Probably each side wanted to hustle the other.

The Mole and Mr. James are memorable characters (embodied by non-actors who are deep undercover in a particularly dangerous part of the real world), and going down the rabbit hole with them makes for compelling entertainment.
