Both Game of Thrones and The Killing drew a lot of attention during their first seasons, and both are back Sunday night to start a second year -- one hoping to build on the momentum from some positive late-season buzz, the other hoping to overcome some negative buzz from last year's cliffhanger.

The AMC series Mad Men -- winner of the Best Drama Series Emmy for each of its four seasons to date -- returns March 25 after a 17-month hiatus. TV critic David Bianculli determines whether it was worth the wait?

The team behind the documentary Planet Earth have teamed up again to explore the coldest, most isolated places on Earth. TV critic David Bianculli says watching Frozen Plant "captures images of so much majesty, artistry, and clarity, it's almost ridiculous."
