The Killing comes back to life on Netflix

Here’s what’s up in the world of TV for Friday, August 1, and Saturday, August 2. All times are Eastern.
TOP PICK
The Killing (Netflix, 12 a.m., Friday): Proving it’s impossible to kill The Killing, the crime drama is returning from the brink of cancellation for a second time. The former AMC program has officially moved over to Netflix for its fourth and final season which debuts on Friday. Although AMC is no longer involved, the creative staff and stars Joel Kinnaman and Mireille Enos all stuck around for one last hurrah. At only six episodes, it will be relatively easy to binge watch the season (which offers a brand new mystery) and still have time to go out and enjoy the sweltering heat of the first day of August.
ALSO NOTED
Gravity Falls (Disney, 9 p.m., Friday): In the Gravity Falls season two opener, the Pines throw a “Mystery Shack Is Back” party and a surprise guest crashes the event. We can only assume it’s Alasdair Wilkins trying to convince everyone to watch this charming Disney animated show. In the meantime, prepare for the return with our Walkthrough of the show’s first season with creator Alex Hirsch.
Hell On Wheels (AMC, 9 p.m., Saturday): With its former drama The Killing airing on Netflix, AMC can devote all its time to the fourth season of this nihilistic Western, Hell On Wheels. Cullen labors at Fort Smith, Durant deals with a railroad accident, and we hope someone gets a puppy or something to lighten the somber mood.
Power (Starz, 9 p.m., Saturday): This Starz drama about a drug kingpin fronting as a nightclub owner reaches the end of its first season. The 50 Cent-produced series has already been picked up for a second season so it’s time to say “see ya later” not “goodbye.”
REGULAR COVERAGE
The Legend Of Korra (Nickelodeon, 8 p.m., Friday)
