New 5-part limited series on HBO, "Chernobyl." I've only watched the first two episodes and all I can say is, "WOW." I knew of the nuclear accident when it occurred in 1986, but I really had NO idea of the extent of the disaster. The Chernobyl accident is considered the most disastrous nuclear power plant accident in history, both in terms of cost and casualties. It is one of only two nuclear energy accidents classified as a level 7 event (the maximum classification). The series is very well done and the cast is excellent. If you have HBO, I recommend this.
