This week is all about endings and beginnings. Peter Capaldi begins his tenure as the curmudgeonly new Doctor on Doctor Who while True Blood meets its true death. And amidst the season finales of Korra and The Last Ship, we get two oddball premieres: Bojack Horseman and the profoundly strange Intruders.

Each episode begins with two teams of magicians going head-to-head with a limited amount of time to create an original routine.
