The 23-year-old Wolfhard spent the past decade making the hit Netflix series, which premiered in 2016 and aired its finale on Wednesday, revealing the fates of the entire Hawkins gang. Aside from his efforts to collapse the Upside Down on Stranger Things, his work has been very SNL -adjacent.

After five seasons, Netflix's sci-fi horror hit wrapped up with an exhausting two-hour extravaganza that, unsurprisingly, delivered lots and lots of … stuff — but very little legacy-building substance.

At the time, “The Rightside Up” hadn’t yet come out, so I didn’t know that the only characters that would die would be Vecna/Henry Creel, Kali and Eleven, who is presumed dead, but really her fate is up in the air. Here’s what Ross Duffer told us about killing characters:

The 'Stranger Things' finale is light on surprises and heavy on sentiment, as the Netflix series bids a sound enough farewell — for now. [SPOILERS]

Warning: MAJOR SPOILERS ARE AHEAD for the series finale of Stranger Things, available streaming with a Netflix subscription now.

Ahead of the finale, the Stranger Things fandom was brewing with speculation as to how the long-running series would conclude. What was initially hopeful anticipation following that explosive reveal at the end of Volume 1 quickly devolved into dissatisfaction among many.
