There's not much in the way of premieres this week, but the fall season is in full swing — meaning there's a whole lot to watch. If you've already finished Stranger Things 2, don't worry, we have more than enough to keep you busy.

The CW's superhero slate is rocking along, with The Flash preparing to introduce new hero Elongated Man. Legends of Tomorrow takes its best shot at a Halloween episode with an installment that should certainly appeal to IT fans. Supergirl is also new, along with Arrow — or should we start calling it The Green Diggle now?

SYFY is also putting up some fresh originals, with horror shows Superstition and Ghost Wars, along with Z Nation and Van Helsing. Fox's Star Trek-esque dramedy The Orville looks to air its most dramatic episode yet, while The Gifted and Lucifer continue their excellent fall runs. Looking ahead to the weekend, there's an all-new The Walking Dead and the latest Star Trek: Discovery on CBS All Access.
