Scientists and filmmakers capture images in unprecedented, truly breathtaking ways in the BBC nature documentary series. Critic David Bianculli calls Blue Planet II a "dazzling piece of television."

Fifty years ago Monday, when Fred Rogers showed up on national public television as the host of what then was a brand new children's show called Mister Rogers' Neighborhood, TV was a lot different. PBS wasn't even a network then — not by that name, anyway — and aside from CBS, NBC and ABC, there were only a few independent local channels to watch, if that.

TV critic DAVID BIANCULLI reviews two futuristic TV shows, one is new, the other has a new season.
