The Next Installment of 'Stranger Things' Looks Creepier Than Ever

Are you ready to return to the Upside Down?

Netflix's sci-fi horror hit "Stranger Things" is returning to the Upside Down — and it looks downright terrifying. 

The teaser trailer for the second season of the Netflix original aired during Sunday night's Super Bowl. The trailer is packed with nostalgia, but it leaves us with even more questions than the final episode of season one.

Where is Eleven? What's happening to Will? Are the monsters really gone? Where did Dustin get that sweet Ghostbusters jumpsuit?

Unfortunately, we'll have to wait until Halloween 2017 to find out.
