The Discovery Channel is "roadblocking" its sequel to Planet Earth, pre-empting regular programming on all of Discovery's owned channels (e.g., TLC, Animal Planet) tonight. I've seen the first episode, Challenges of Life, which airs tonight at 8:00 E.S.T.)and can confirm that if you liked Planet Earth and are interested in animals of all kinds, you won't find too many more compelling shows on TV, especially in high-def. If you don't have high-definition TV at home, barge in on your friends. Immediately after the first hour of Life stay tuned for the second, "Reptiles and Amphibians."
