It's a week of familiar favorites this week, led by what should be a fascinating shake-up on The CW's Flash. Iris will be speeding in to save the day, and she's bringing a whole lot of new TV with her.

Along with Flash, The CW is also dropping a new Black Lightning and Legends of Tomorrow this week, and the network also has a fresh Riverdale and iZombie. Fox has a new The X-Files, with a story digging into the macabre and organ theft (a recipe ripe for a classic Mulder and Scully story), plus new Lucifer and Last Man on Earth. Fresh off its 100th episode, Agents of S.H.I.E.L.D. is back with Coulson and his team still trying to save the world.

At SYFY, the network has new episodes of The Magicians and Channel Zero: Butcher's Block. NBC is dropping a new Timeless for the weekend, and AMC is back with All Out War still simmering on The Walking Dead.
