"Alzheimer's: Every Minute Counts" is the first TPT production since 2013's "Constitution USA" that all PBS affiliates are required to air — understandable when you consider how its subject matter touches most of us in one way or another. The documentary sheds light on the consequences for the nation if a medical breakthrough isn't discovered.

Aaron Paul could have cashed in on his "Breaking Bad" success with formula action films or a network sitcom. But the young actor has continued to take chances by producing and starring in Netflix's "BoJack Horseman" and Hulu's "The Path," a drama about the power of cults that returns for its second season. The choices may not lead to more Emmys, but they indicate that this is a young man more interested in challenging himself than building buzz.

"The Magicians," which returns for a second season, takes place at Brakebills University, a sort of graduate program for Hogwarts students who are ready to add more tricks — and more trouble — to their arsenal. In upcoming episodes, the main characters are transported to Fillory, a kingdom where frivolous activities like Quidditch are strictly prohibited.
