HIGHLIGHTS

Happy! Season 1: The first season of SYFY’s comic-based dark-dramedy series is about to be bingeable. The show follows a washed-up cop who sees an imaginary creature that helps him try to track down some missing kids. It’s twisty, darkly funny, and a lot of fun.

Travelers Season 3: The third season of Netflix’s Travelers continues the twisty adventure of a team of time-traveling heroes sent back to the present to try and save the future. The show is fantastic, and largely flew under the radar upon release. With the third season coming, it’s the perfect time to catch up. As for genre pedigree, the show comes from a former producer on Stargate SG-1.

24: The Complete Series: Jack Bauer is back, baby. If you’re looking for an action-packed long-term binge, the entire decade-long run of 24 will be ready to roll. The show inspired countless imitators and helped establish a lot of the action beats we see every day on TV.

Runaways Season 2 Premiere: It might not get the buzz of a Daredevil or Jessica Jones, but Hulu's Runaways is definitely holding its own. The comic adaptation follows a group of kids who discover their parents are super villains, so they go on the run. Season 2 really picks up in the meat of the comic storyline, and should hold plenty of action.

HIGHLIGHTS

Event Horizon: It’s a sci-fi horror classic, and it’s hard to believe the flick is now more than 20 years old. Not surprisingly, the cult classic has aged pretty well. If you want some throwback, 1990-era scares you could do far, far worse than this one.

Mars Attacks!: It’s a schlocky, tongue-in-cheek mess loaded with celebrity cameos from the era, and this one has aged pretty terribly. But still, it’s a lot of big, goofy fun.

Hereditary: One of the biggest indie horror hits of the year is finally coming to streaming. Fair warning, though — it’s absolutely terrifying and will probably make your skin crawl. In a good way. Just, you know, be warned.
