Chapter Five: The Flayed - S3-E5
Audio problem: When Joyce, Alexi and Hopper go to Murray's, Murray points a double barrel shotgun at them and it makes a sound of a pump action shotgun.
Chapter Five: The Flayed - S3-E5
Continuity mistake: Eleven and Mike are sitting next to each other at the hospital. Eleven looks to her left in one shot and the camera changes angles. She's now looking straight ahead and immediately looks to the left again.
Chapter Six: E Pluribus Unum - S3-E6
Factual error: When the Russian requests the cherry flavor and refuses to talk, he gets thrown out. At the back is an oil drum from the French energy company "Total." However that logo was introduced only in the mid 2000s. (00:11:55)
Chapter Six: E Pluribus Unum - S3-E6
Continuity mistake: When the librarian picks up the phone he picks up the one in the middle, in the next shot we see he has the one to the left and when he hangs up it's the one in the center again.
Chapter Seven: The Bite - S3-E7
Continuity mistake: At the very beginning the band the camera pans by is totally different from the one standing behind the mayor later on. For one there are no more clarinet players, a cymbal player suddenly appears right behind where the mayor stands and the drummers are 3 totally different boys, with the 3rd from the right missing his glasses suddenly and the second drummer being much shorter. (00:00:40 - 00:01:15)
Chapter Eight: The Battle of Starcourt - S3-E8
Factual error: Because of the way radios work, when Suzie and Dustin are singing their duet they wouldn't be able to hear each other and the rest of the party would only hear a garbled mess. Per frequency only one radio should transmit at each time, so all the others can receive. If multiple radios are transmitting simultaneously, the signals will overlap and result in unintelligible noise. (00:35:53)
Chapter Eight: The Battle of Starcourt - S3-E8
Factual error: The value of Planck's constant used in the show, 6.62607004 is the value that was measured in 2014. The value that was in use in 1985 was 6.626176. The value was updated again in 2018, to 6.62607015.
Chapter Two: Vecna's Curse - S4-E2
Continuity mistake: After Mike kisses El on the forehead, Jonathan is in the back grabbing his glasses from his pocket. In one shot, he's grabbing them out, and then the next shot has them at waist-level.
Chapter Five: The Nina Project - S4-E5
Continuity mistake: The seat belt keeps appearing and reappearing on Nancy's shoulder as she's driving.
Chapter Seven: The Massacre at Hawkins Lab - S4-E7
Continuity mistake: Eddie is still wearing a denim vest he took off his body and threw at Steve a few seconds earlier. When the camera cuts away and back, the vest is gone again. (00:15:19)
Chapter Seven: The Massacre at Hawkins Lab - S4-E7
Other mistake: When Hooper was trying to light the alcohol-soaked rag to make a torch, his lighter wasn't working at first. He finally got a flame at the last minute. However, the sparks alone should have been enough to ignite the flammable rag. (01:00:33 - 01:02:03)
Chapter Seven: The Massacre at Hawkins Lab - S4-E7
Plot hole: The upside down should be mirrored, i.e. all left is right and right is left. When the team finds a gateway where Chrissy died, they should be seeing a mirror image through the ceiling. Also, all buildings should have been reversed. Directions to get there on the bike would have been confusing and reversed, and when any writing was seen in the upside down, it would have been backward.
Continuity mistake: Eleven makes the helicopter fall from the sky and blow up some army vehicles. Within a cut, it's much earlier in the day as the sun is right above her. Prior to this, it was lower in the sky and returns that way as she and the rest of the crew are driving away.
Answer: Technically Steve was never intended to die in Stranger Things. The Duffer brothers wrote a pilot script for a miniseries called Montauk that would eventually become Stranger Things. In that version of the story Steve is a more overtly villainous character and is killed by a monster. The Steve character was reworked once Stranger Things was created due to Joe Keery's more likeable approach to the character.
