Wild Korea on NatGeo Wild.
2 episodes, "Voices", on wildlife in the Republic of Korea, and "Life at the Borderlands" abut wildlife in the DMZ.
The wildlife stuff is good, learned a few things (they have lightning bugs in Korea? I spent almost 10 years there and never knew!)
Nitpicked a lot of Korean history, especially on the "Borderlands" episode.
Narrator for "Borderlands" is a Brit, and I winced every time he said "Dee Em Zed." (Although American amateur radio operators often say "zed" instead of "zee.")
Understood almost none of the Korean-language narration, combination of lack of practice, local dialects, and specialized vocabulary -- I was not exactly spending a lot of time learning about the blue speckled mud skipper...
Mrs. Drang commented that their cinematography could have been better: She said she watched the mating dance of the red crowned crane as a docent at the Woodland Park Zoo in Seattle and it is far more spectacular than depicted here.
