The holiday season is getting closer, and that means quite a few shows are going on hiatus until the new year. But there are still a few major events on tap — including the Arrowverse's annual crossover, with 100 percent more Superman and Batwoman.

The big story this week is the conclusion of The Flash, Arrow, and Supergirl's "Elseworlds" event, which formally kicked off this past Sunday. It finds the Arrowverse's greatest heroes heading to Gotham City to try and set reality right, and if things go well, it could also spawn a Batwoman spinoff series. Looking to SYFY, the sci-fi horror thriller Nightflyers, based on the George R.R. Martin story, wraps up its binge-friendly 10-episode season this week. The show has run almost daily, and in case you missed any episodes, it's also available on the SYFY streaming app.

Though not every Arrowverse show is part of the big crossover, they're all new this week. Legends of Tomorrow is crossing over with itself (kinda) after Constantine blew up the time stream; and Black Lightning is also fresh. Starz has new episodes of its genre-friendly lineup of Counterpart and Outlander as NBC drops a new Midnight, Texas. If you're in the holiday mood, AMC has several showings of holiday staple Elf on tap (we've highlighted a prime-time airing below). Because Christmas is never complete without seeing Will Ferrell in that elf suit at least once in the season.
