I used to enjoy Discovery Channel shows but lately I've all but lost interest in favor of BBC, ITV, Smithsonian, Al-Jazeera, and HBO for Last Week Tonight. PBS Frontline is still pretty good, but it seems like Discovery Channel, History, and Nat Geo seem like they're producing shows of lower and lower quality.
