Super Dark Times (2017)
 

I highly recommend this one and would like to talk about it.
But I can't without spoiling it for you.

So watch it BUT don't do any research!

If you look it up, you get a summary that spoils things.
This is one of those the-less-you-know-the-better movies.

All I can say is that it's about some teenagers and it's set in the nineties.
