'Stranger Things' Season 2 will have 'more horror'

If you recommended Stranger Things to friends with the missive "Don't watch it alone at night," you aren't alone. After several episodes, we got used to the pulsing music and traces of the Demagorgon, but we'll need our wits about us for Season 2.

"There are going to be some challenges the characters face that are real, that are disturbing," actor Finn Wolfhard (Mike) told Emmy Magazine. "This season will be a lot more dark, a lot more horror-oriented. I think people are going to like it better than the first season."

"I think they're all very emotionally scarred," added Gaten Matarazzo, who plays Dustin. "They feel a little bad because their best friend is back and he's not acting like their best friend anymore. He's changed."

In February, the Duffer brothers revealed that Will Byers (Noah Schnapp) is having visions of the Upside Down, so we can see how that would complicate things for the squad.

Stranger Things Season 2 will hit Netflix on Halloween.
