Anybody been watching this? I really like it

The bit last night where they visited the Rwandan church was awful. All those skulls racked up like that, many split in two and even one with a spear left pierced through the top...

Anybody more intelligent than me know much about the current Rwandan President that they visited? I'm assuming he can't be that dodgy, or the BBC would have been hesitant to show them all meeting him
