It's Westworld's world, we're just living in it. The buzzed-about season premiere of the high-concept series is finally back this week, promising more robo-cowboys and a trip to Shogunworld. 

Aside from HBO's acclaimed hit, The CW's superhero line-up gets a few shake-ups this week, with one series wrapping its run and another returning from a lengthy hiatus. There's also a whole lot of other new stuff, too.

The CW's newest addition Black Lightning wraps up its first season this week, but don't worry, he and Thunder will definitely be back next year. Supergirl is also back from exile this week, after clearing off the schedule to allow Legends of Tomorrow to take its slot. With Legends' latest season complete, Kara is back with all new adventures.

SYFY also has some new episodes this week, led by a new installment of The Expanse and the latest Krypton. AMC has a new episode of The Terror, plus a new Fear the Walking Dead (now with 100 percent more Morgan). ABC is also dropping a new Agents of S.H.I.E.L.D., as the series heads toward its season (series?) finale in a few weeks.
