WARNING: STRANGER THINGS SPOILERS AHEAD (AFTER THE TWITTER AUDIENCE REACTION - DON'T SAY YOU WEREN'T WARNED)
Not only has it become the most watched series but it's also trumped any other film on the streaming service.
Four days after the long-awaited series touched down on Netflix it had been watched by 40.7 million household accounts with 18.2 million finishing the entire eight episode season already.
We can't say this is all that shocking, in fact the shocking thing is that there's still people that haven't finished it.
Naturally, when a series finishes everyone starts banging on about the next one. Stranger Things is no different - in fact, if anything it's worse.
But, with another potential long wait for season four, fans are already pulling together theories and discussing what they reckon might happen next.
One of the most popular fan theories is centred on perhaps the most shocking twist in the season's finale - the death of beloved Jim Hopper.

In case you've had some sort of amnesiac episode and can't remember, poor Hopper (David Harbour) looks to be brown bread after Joyce Byers (Winona Ryder) was forced to detonate the machine that kept the gate to the Upside Down open.
It seems very unlikely that our pal Hopper managed to survive such an explosion, right? Except for the little post-credit scene in which a couple of Russian guys make reference to an unseen 'American'. Could that be Hopper? Well, plenty of people seem to think so.
Speculation from fans suggests that Hopper was able to escape into the Upside Down, dodging the explosion, and was able to reappear through another portal in the USSR, hence him being captured by soviets...
